Confused (No search results)

I am using Windows Vista and have had LimeWire for awhile, but one day I get on here and type in a song and nothing comes up... at all. This has been happening for about a week at least and I'm going insane. I tried uninstalling and reinstalling, but that didn't work. I don't really know what to do. It worked before and then just all of a sudden stopped and I haven't added any security things that weren't on the computer before.
