Is that the exact message ?

Also please provide more details on setup

On that one Limewire is installed and just won't run properly, but you get the idea right ?

Also please include what kind of antivirus/spyware software you use, and how your firewall setup is like. It really seems like something is blocking Limewire.

Also are you logged in as an administrator or just a user with some privileges ?
