this works great.

thx

princessamy86 it seems the school has blocked port 6346 which LW uses by default, else, something on your computer is blocking that port. Which sounds like a firewall. (The school may have recently changed their policy on bandwidth use. I'm sure they can detect gnutella & other p2p network programs running on the school's network.)

Go to LW's menu bar, Tools>Options>Advanced & change the listening port from 6346 to another. Also, I doubt UPnP will work I don't know. Try setting it to manual port forward. And also change the port no.
Try these ports: 1111, 80, 3500, 4008, 1203, 10000, 15189, 20282, 22817, 443, 427, 34599, 40475, 64049, 20-22. You should probably use the same port no. for both listening port & manual PF port.

You'll need to press the apply button after the change. I'm not sure whether you need to relaunch or not. But go to File menu > Disconnect. Wait a min, then File>Connect. Give each port you try at least 15+ mins to try to connect.

I have just found out that the Uni blocked the ports last week so was a coincidense I'd bought a new laptop

Sorry if I'm posting in the wrong place, but I'm new and I've got a problem. I have a laptop, Windows XP, and it had limewire 4.8 (or whichever version came before 4.9), and it worked fine. Then, I downloaded the new version, and every time I try to open limewire, it just shows that opening screen and says,

"LimeWire was unable to initialize and start. This is usually due to a firewall program blocking LimeWire's access to the internet or loopback connections on the local machine. Please allow LimeWire access to the internet and restart LimeWire."

Now, I need to mention that I'm not very skilled when it comes to computers. I tried a few things, like restarting and taking off the Windows Firewall. I took a look at the LimeWire help, and it only gives directions on what to do from the limewire screen... but not even that loads. I just get the logo and I have no idea how I'm supposed to configure it and stuff...

Help!!

Rather than disable your firewall, it's much safer to configure it. Did you configure your firewall so it allows LW full access (advisable not to have 2 active firewalls b/c they can interfere with each other); Firewall configuration instructions (click on link)

If your firewall is already configured, then just let LW do the rest when you come to the firewall configure part when 1st opening LW. But yes, LW 4.9 is much more sensitive to firewalls than LW 4.8.1 was.

1. OS version? (eg: Windows 98)
2. What firewalls you have?
3. Connection type? (eg: dialup, broadband, cable, etc.)
4. Modem & router brand name & model numbers?
5. Where are you trying to connect from (home, school, work, etc.)?
6. What version of Limewire (LW) & Java do you have? (Go to LW's menu Help>About LW...) Will show both LW & Java version.
7. Who is your isp provider (Internet Service Provider)?
8. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up.

hI Guys,

Well , I have been reading this topic for hours but I can't find the solution for my connexion probleme with limewire

To resume my situation:

Like 1 month ago, limewire decide to stop working 'it say that I am firewalled' and it can't connect to the network

*I use win XP SP2

*My connection is broadband t1 cable direclty connected to the bulding network

*I use only one computer

* My firewall is well configurated (kaspersky with 6346 ports both udp & tcp open, the test ' http://www3.limewire.com:6346 ' say that Your test worked! )

*the windows firewall is off

* I called my isp customer service (mdi access chicago), they told me that no ports has been blocked for p2p

* I have installed limewire 4.10 and java 1.5

Only 1 block is green from the connection quality and limewire still detect a firewall!!

I can't find any solution

Thanks for your help

paolini what's changed since it was working? And what have you tried? It might sound very basic, but try deleting your LW Preferences folder whilst LW is closed; instructions here: Point #2 in Fixes for Limewire (sample at bottom of page.)

What modem/router device brand name & model number do you have. See if it has a UPnP (Universal Plug & Play) switch on the outside. If you know how to log into the device using your browser, check to see if there's a UPnP option. If yes, enable it.

Thank you Lord Of the rings for ur reply

Well I try severals times to delete LW preferences but it didn't work

Since aproximatly a month, I launch LW on day and it say that it can connect to the network because my computer is probably firewalled but I didn't change anything on my configuration and my firewall, I disable it and nothing change, trying many ports, forwarding...nothing!

I don;t use a personal router or modem, I am directly connected to the swich board of the bulding, unless they install a hardware firewall to lock P2P transfert, I don't see, I called the ISP but they said that they don't change anything in there config

I try other gnutella software like sharezza , morpheus but same thing, it's seem like I can go anymore to Gnutella network

paolini With LW 4.10.x & later, LW now has a preferences folder in a new location. It might be worth trying to delete it also whilst LW is CLOSED!
Use your search function, go to options & change view mode to show "hidden" files & folders. Then search for limewire
It's found here: C:\Documents and Settings\username\Application Data\LimeWire
The Application Data folder is "hidden".
You can see an example of how to find & delete it from a FrostWire example here: How to delete your FrostWire Preferences folder
But of course, it's the limewire folder you search & delete. Check that the one you select is from the above location (ie: within the Application Data folder!!!) And of course only do it whilst LW is "closed"!

If this doesn't fix it, well I don't know. You could try other ports. Here's a list of several to try: 1111, 3500, 4008, 1203, 10000, 15189, 80, 88, 8080, 8000, 20282, 22817, 443, 427, 34599, 40475, 64049, 20-21, 3689, 631, 139, 548, 19515, 22091, 25079.

ie: Go to LW's menu bar, Tools>Options>Advanced>Firewalls. Change the listeing port to one of the above. Also set your port to manual port forward & change the port to the same. There's a lot of ports there but if you're determined to get LW running, then it's worth the persistence. Don't forget to press apply after making any changes. Then go to LW's menu bar, File>Disconnect, wait a minute, then File>Connect. Give each no. at least 20+ mins to try to connect.

Failing this, you could try proxy options. There's different types. A Fix for those whose ISP's block Limewire pages 1 - 3 which have links to alternative instructions.

Windows XP can't find no such dir Preference or file??? Looked everywhere.
