Cant connect.
 

Ive added LimeWire and Gnutella as connections under my firewall and I have taken them down and re-added them and I still cant connect. Ive been having this same problem for atleast a month and a half and Im getting really angry.

Help, please..

First thing to try: Delete LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).

This will kill all of your settings within options, you'll have to go back through afterwards & reset things. If you're not sure of your settings, go through LW's tools > options & write them all down, so that you can reset things later.

Next thing to try : Reinstall Java & use this version. Use the JRE offline installer & remove your current Java version(s) before you install this one.

In your other thread, you said that you have a wireless router...what's the brand & model???

Im not sure how to delete the preference folder :( I dont know where to go to delete it.

My wireless router is netgear, and I think the model is WGR614 v5.

Ive been using LimeWire for atleast 3 years and Ive never had any problems until now..

It just randomely started working...I want to make sure its the one I paid for versus the free one..Can I contract virus' from the free program?

There are lots of infected files being shared on the network. It's just as easy to download an infected file with LW Pro as with LW basic;)

Make sure that you have a good, updated AV & scan files that you've downloaded before you open them! If you don't have an AV, have a look at the link below.

Sorry, I forgot to include the link for deleting the prefs folder. If you need to do that in future, see points 2 & 3 of the link below. If you've used older versions of LW in the past, there could be a folder in either location.
