It's probably a fake file. Is it a new release or really popular file? Does it have heaps of sources (up to 100)? This kind of fake has only appeared recently. Search again, look for a file with 10 sources or less. Even go for a modem source... it will just take longer to download.

If it's a video file, look it up before download with Bitzi (music files aren't often rated with Bitzi but a lot of video are).
