Divshare acts very weirdly with download managers. If you're using one, turn it off and try again. I had the same problem until I disabled my download manager.
Unfortunately, it turns out that the copy of the movie I got ahold of was mislabeled and is actually a PAL copy, so now I have to wait for the PAL verision of the riff to be done so I can watch it. Bloody stupid regional differences...
