Gnutella Forums - wont even open

I wa susing Limewire 2.1.1 this morning fine and when I came home this afternoon, it won't even open. The only thing is I ran a virus scan and detected a trojan in a Medal of Honor key, which I never used or opened.

So I tried donloading 2.4 and I get the initial screen and "loading messages" and then it stops responding???

I can see the new version not opening due to internet conn. (yes I read FAQ) but the old version would open and then establish DSL connection. Now 2.1 does nothing. and 2.4 stalls aftler limescreen??? ANy Ideas??
