Itunes downloading file problem?

[Yangggdf Dfsdf]

I keep getting the error that says the file is corrupted and I should try again.I have tried again but no luck.It can't be my firewall settings or anything because just before I downloaded two songs with no problems. I read that you have to delete the corrupted file to try again but I can't see it...I'm using windows 7 if it makes a difference.I've tried to download the song multiple times and I'm not paying for it again.

It's possible the file you're trying to add got deleted, then itunes would look for it and say it's corrupted because it can't be found. Download that song again and see if that works.
