I have the latest version of LimeWire (4.0.4 I elieve is the latest). I use Windows XP and I have downloaded every patch and update available. I don't think it has anything to do with my system. The files download, but when they are corrupted they have gaps in the music or sometimes sound like a CD skipping. If I put them on a disc, the corrupted files will not play on my home stereo (which plays MP3s).
