Unfortunately, the problem is not solved...
I get the exact symptoms as before: LW working, then no connection, warning on Event View saying "Tcpip", shut down and restart LW, only Lime-window appears etc

In addition to that, every time this happens with LW (After LW having stopped downloading and me shutting it down) I cannot view ANY website on internet explorer, although Im still connected, I get the usual "page cannot be displayed" and "server not found" messages, while when LW was WORKING, I could visit every webpage and it was fine........

I have shut down the windows firewall, and on McAfee LimeWire continues to have full access to the net. When the problem ocured again my preferences where (after having deleted the preference folder): downloads limited to 4 max parrallel downloads, uploads to 2 per user and 8 max..is that still too much?
My speed was unlimited both for downloads and for uploads, ultrapeer function deactivated but OOB search on.... does that cause my problems? (My connection speed is 786 kbps broadband)

I have also discovered that I can open LW and have it disconnected from the Gnutella network, and that way I can shut it down and open it again as often as I want without an effect on the websites on internet explorer, therefore LW causes the problem only after having been connected to Gnutella network for some time, but in which it is working just fine........help....?

Allright, now is the time for me to say: WTF??

LW window is open BUT I have pressed the "disconnect button", all my bars are red, the "connect" button is visible - all signs of me being disconnected from the network....... but LW is CONTINUING downloading and uploading!

I get the changing "time left" indications, the kbps and the percentages of my downloads growing..........

what is happenning now?!?

OK. Been there, done that. Never figured out what was wrong though. The only difference is that I could still use the internet when it happened. I updated and it was fixed.

There are a few things that I found helped a little.

1. find a download that has trouble downloading. Something you know is legit though (not spam). use the find sources and resume on it until it says awaiting sources.

2. In you monitor window check the box for show incoming searches.

If this makes no difference for you what-so-ever then try a complete clean install of both Java and Limewire. It just might help.

I mean everything. Uninstall Limewire using Start>Programs>Limewire>uninstall

Then do a search and delete everything Limewire related (not your downloads off course ) including preference folder, incomplete folder, themes etc.

Remove all java through add/remove programs and then reboot your PC. If you have a registry cleaner then use it to find traces of both programs (there is no need to delete other entries then for these programs) Then reboot again

Now reinstall Java. Current version is now 5.0 update 9 I see. Choose this one Java Runtime Environment (JRE) 5.0 Update 9 and choose the offline installer

Download Limewire again from www.limewire.com and again choose the offline version.

Install Java first and then reboot again before installing limewire.

Hopefully that should work.
