Strange archive.

So last night I set a file to download (0443 - The Amazing Spider-Man (U).rar [3ds]). When I checked it this morning, it was ready to go. I extracted it and immediately received an error. I checked the contents of the archive and it contained 1 .3ds file, but the size was listed as -2,000,000,000b or so.Can someone explain what is going on?

it got corrupted during download, try again.
