So you previewed part of the file, so it isn't corrupt?
You downloaded succesfully other files so it isn't corrupt?
You won't try another client that connects to exactly the same network, because it isn't corrupt?

Good luck with that

If I remember correctly then Limewire should be able to display how much corrupt data is being sent by rightclicking the file and selecting something which I can't remember.

P.S. Ever thought about that just maybe the file is ok but the host(s) sharing are sending bad data?
