Cannot Connect (prolly tired already huH?)

lol I know there have been a ton of posts about not being able to connect, but I've looked through all of them, all the FAQ's, searched on google, done everything, and..........i still can't connect.

I have tried running the .jar file, I have tried changing my ports to accept all ports on TCP and UDP and protocols, and almost everything else.

I am using windows 2000. I install Limewire, and when I start it, I can't connect. I couldnt figure out if limewire is a win XP program only, and would like to know how to fix my problem if it isn't.

Please help =)

Thank you in advance!
