Hangs at "connecting . . ." when downloading mp3s

Hey, I seem to be having a slight problem with Limwire. I don't have any connection problems really. The problem is that I can't seem to be able to download any kind of mp3 or movie file with LimeWire. When I look up a file, choose which one I want to download, the download status will hang at "connecting . . .". I've noticed that same seems to be happening with other p2p programs as well. This is driving me crazy! Please, help!

BTW, I'm using ver. 4.12.3 PRO. This is an S.O.S! I thank you !
