I too am having the same issues....Mac 10.3.9, using the current Limewire and files keep disappearing!!!! I download, wait a few days and when I try to play them again they aren't there!! Glad that I didn't pay for this! Switching to Frostwire and will pry THAT works. Can't find an old version of Limewire (2.2.1). Anyone know where I can get a copy? I'm thinking about doing batch downloads and burning to a CD then reimport to iTunes. Does anyone have any thoughts on this?
