Yeah did the test, it said "true" so at least Limewire is accepting incoming connections.

What is weird is that I can occasionally download a song, so I know it does work, on rare occasions. I'm going to start paying more attention to the sources that yield the few successful downloads and see if I can find a pattern.

Still seems very odd that files with like 52 sources won't download or give me "need more sources" error. How many sources do I need, 82?

By the way I am on a school network. I'm pretty sure they have installed a firewall on their servers for security reasons and I'm thinking that may be part of the problem. I'm a little wary of contacting the system admin(s) about program access though. Last time I told them I was "having a problem with downloads" and they told me they have blocked some P2P programs such as WinMX because it "encouraged illegal file sharing" and that I shouldn't be using these types of programs on their network. This is probably why WinMX stopped working a few months ago. I fear they may also be blocking or inhibiting Limewire in some way also. They have also placed large bandwidth restrictions on our network. Basically they're trying to do everything to ensure we can't download MP3 files.
