An unknown error occured (-50).

A movie I purchased stops downloading almost immediately and the error message above comes up. The rest of iTunes works properly and my internet connection is fine. I was downloading numerous TV episodes before and during while this movie was in the cue without any issues. I've restarted my network and that did not seem to fix it.

I've deleted the movie from the cue and re-downloaded it but still same issue.

Any solutions out there?

Thanks in advance.
