I went on Limewire yesterday and tried to play my music library in the limewire player, but it came up with a message saying 'Limewire cannot play the file ...(name of song).... The file type is not recognised'. I haven't changed any settings or anything and it's said this out of the blue, it keeps saying it when i launch or preview a download too, does anyone know what's wrong and how i can change it?? Thanks!
