Start off by changing listening port

Also, check that the Windows firewall's off & that McAfee's allowing LW. There's more info about configuring McAfee here: Port Forwarding for the McAfee Security Center

Many schools don't allow p2p use. You should check with your school to see whether they do or not. If there's no problem with the school allowing you to use LW, ask around & see if other people can use it without a problem.

Do you have an external modem/router that plugs into your computer, or that you connect to wirelessly (might be in another room at home)? If you do then we'll need to know the brand & model.

I checked my McAfee Firewall sittings and LW has full access. I checked with the school and other students. Apparently I am the only one having problems. My laptop has an internal wireless modem. I tried hooking the computer directly into the modem and still get the same thing.

Have you been able to use any other versions of LW on this computer before?

After you deleted LW's preferences folder, did you have to go through the setup wizard again?

Go & find the gnutella.net file - how big is that file?

Which version of Java are you using now & did you try the older Java version?

Did you try a few different ports in the range mentioned in the help thread?

This is the thing. I am on a brand new laptop. The one I had before this one crashed. The cooling fan quit working and the mother board ended up frying cause it got too hot. So with this new laptop I went from Windows XP to Vista. I have not been able to run any version of LW. Nothing I have done has worked. The computer came with a free trail of Napster already installed and it ran fine no problems BUT I am not a fan of napster so when the trail ran out I uninstalled it and installed LW. I tried the frostwire too and having the same problems. The file was like 25.3 MB, not all that big. As far as Java goes I am kinda stuck with Java 6 cause I need it for other programs I have and use. I tried an older version but the other programs weren't working right and kept asking me to upgrade. Regardless of the port I use I still have the connection problem. There has to be a simple solution to fix this ...

I have a desktop & laptop both with limewire pro. I can get turbo connection on my desktop but one one little green bar (starting connection) on my laptop. My firewall allows limewire. I did get turbo connection once on my laptop but cannot even connect to limewire at all. I am very frustrated with limewire. I have uninstalled & installed limewire a couple of times not. I have the most recent java. WHAT CAN I DO TO GET LIMEWIRE TO CONNECT ON MY LAPTOP. I have windows vista.

Do you mean that the gnutella.net is 25.3 KB ( if it's MB then there's something very wrong)?

You said that older versions of LW "weren't working right & kept on asking me to upgrade"...older versions will always ask you to upgrade. If the older versions were connecting then I'd go with them (ignore the upgrade nag - that's just LW trying to make money).

I don't know if I can help you any more. The deleting of prefs folder is very often the simple solution but you don't seem to want to tell me how that went, so... I don't have a clue.
