yet another connection problem
 

just downloaded limewire onto imac osx, and won't connect, green dot flickers before going red again. i've got no firewalls or anything on. yet. also, i dont have a 'connections' button, looks like i should have.
it's not the service provider, the pcs can download grokster, morpheus etc no problem. help, what can i do?

It could be the ISP some ISP's block gnutella but they don't block fasttrack.
