Limewire used to work but now it doesn't. It has an excellent connection but when i try to download all I get is need more sources even if there are 90+

I run Windows XP and it recently installed an update and a firewall on my comp, i thought this could be prob so turned it off but didn't work. The problems only started after the limewire update 4.2.6.

These are my connections (T1 i think on a uni network):

Local Area Connection - Realtek RTL8139/810x family fast ethernet NIC

1394 Connection net adapter

Have tried deleting .limewire folder, did a bug report thing said false, downloaded a new java thing, did something like writing gnutella and writing some port number and adding it to a list

tried to install winmx cause had given up on limewire and it said:

"win mx is unable to receive incoming TCP connections from the internet. This could be due to many things, such as settings in your operating system, a software based firewall, the use of a proxy server, or a broadband router/firewall. Depending on your exact configuration, you may be able to open or forward an incoming TCP port, but it is not required."

I realise it says this is not required but could this have something to do with limewire problems or not can anyone suggest anything my firends on the same network can get file sharing programmes to work??????

Just tried and win mx doesnt work either can someone please help
