Repairing fucked audio files

Greetings all

I recently downloaded an audio file that leaked last week in the Smashing Pumpkins community. The file is an unreleased studio song that is unavailable in any other form. Problem is that the track (and remember this is the only circulating copy) is fucked beyond belief after a few minutes and skips relentlessly. Opinions of the artist in question aside, does anyone know any utilities that could help repair the file? At the moment it's virtually unlistenable once the skipping begins. Have a listen and see what you think!
