hey I really need some help.

I am currently using bearshare and after upgrading it this past weekend, it no longer connects. It simply says that Bearshare is unable to connect and that I should try again later.
I had no problems until I upgraded.
So I tried using Limwire and it didn't work either...however my room mate's limewire does.
I'm at college right now and I'm behind this thing called Websense, but the thing is that I ahve never had problems liek this before!
Please help.
