Better question is this...why in hell are you still using Limewire? Havent you noticted that Limewire has got sued recently? With that said, here is a way to free up your resources.....remove Limewire from your comp.
Right now, the best sources are Bittorent or newsgroups(this actually costs money). Both of these have extensive info here on aD, and there are several stickies on bittorrent.
Or use Frostwire, which is made by the same people as limewire, but is spyware free, and can't be sued due to it's licensing.

Thank you both for the info, I will look into both of these P2P clients. I have been using Limewire Pro, and I had thought that if I paid for it, it would be bettter. I was sooo wrong.
