Do you by any chance have any old installers.

You could try reverting back to an old version to see if it helps

No I don't, But the problem first occured with the old version of PRO that I had. So I uninstalled it and installed the new basic version. But that didn't change anything.

Could you tell us what settings and numbers you use in Limewire

Tools>options>Advanced>Firewall Config

and also if you get no connect at all. (Look at your connections) do you see UltraPeers trying to connect nut changing all the time or do you see nothing at all.

I Have it on UPnP right now and it has 36591 as the listening port. But I have tried doing manual to and that does not help anything. For manual I have tried several different ports. Nothings works. And as for if it connects at all or not, when the problem first started it would connect for a few seconds and then quit. Now it just doesnt connect at all.

Sounds strange. If you are absolutely sure that nothing is blocking Limewire on your end, then try scanning your computer for malware, and after that do a clean install of both java and limewire. Use the offline installers for both.

When uninstalling Limewire use the Start>Programs>Limewire>uninstall and then do a search for Limewire afterwards and delete everything except your downloads. If you keep your downloads in the default shared folder then move it somewhere so it isn't registered by Limewire on the new install. Delete the incomplete folder as well.

Then after removing Java as well, reboot your computer and scan your registry for entries left behind by either program and delete them. Reboot after doing this. (note: remember to make a back up just in case you delete some entry you shouldn't have)

If you do not have a registry cleaner then try this one: (By the way this little program is quite good for many other things as well)

Now download Java and Limewire. For Java try this one Java Runtime Environment (JRE) 5.0 Update 9 (Remember offline installers for both)

http://java.sun.com/javase/downloads/index.jsp

www.limewire.com

Install Java first and then reboot before installing Limewire

If this still does not work then I would seriously start thinking about calling your ISP's help desk again.

BTW I would not keep running Limewire unprotected. When you get it back up and running start adding all your security. Firewall, antivirus and router back into the mix.

Actually I have already reinstalled both java and limewire several times. And as for the malware I have scanned my computer several times with multiple programs, I do this on a regular basis. One more thing I guess I forgot to mention is that I know this is not a problem with the computer itself, the reason being that all of the computers on my network started having this problem at the same time. This makes me think that it is either a problem with the router or the ISP. I don't see how it could be the router since I have done everything with it to make it accept limewire. And like I said earlier I even bypassed the router once and connected directly to the modem and the problem still existed. This is why I am almost confident that it is a problem with the ISP, but they insist that they do not filter or block anything from running. I even specifically asked about limewire and the gnutella network and they said no they do not block that or anything else. I'm getting so frustrated by this.
