Corrupt file, but no one else had any trouble

Is it possible that if you try to download a file from the site that thousands of people are downloading at the same time, that the file you bring out may be corrupt? I downloaded a game that wouldn't come out of it's RAR file because it said it was corrupt, and yet in the comments for it, everyone else says they got it just fine.(edit:Please move to Download problems. I didn't notice that section until after I posted the question. This forum's set up is confusing sometimes.)

Redownload it/use a download manager.

yes, its entirely possible.
