Cannot download anything since getting premium.

I just got premium today (through invites and not purchase) and all of sudden downloads will not work. I try to download something and have to keep clicking "retry download" since there is repeated errors and it works for a bit, but then at the very end when the file is nearly done downloading the "download error" message constantly pops up and no matter how many time I click retry download, the file refuses to download. I'd like to add that I just downloaded a movie yesterday and did not have premium.
