Unfortunately, it seems that Limewire is the only program that causes me these problems. I've downloaded other P2P programs and all of thier exe. files open fine. Does Limewire come with any spyware that might be hard to remove? I can't think of any other reason why this would happen.
Anyways, I would really like to get Limewire working again because the other programs don't have nearly as many files. This is definitely a strange problem.
