I purchased a movie and the entire 2nd season of Lost 2 days ago, as I am getting ready for a trip overseas. I get err=9006 with every attempt to download these files.
It's not a local firewall/av problem, nor is this an ISP issue (I can transfer large files all day long from anywhere else).
Just for kicks I went and bought a song to add to my download queue. It downloaded perfectly. I then immediately tried downloading one of the video files, and sure enough... it failed (this was one I had not previously tried to download, so there isn't a cache problem).
Here I am trying to plan ahead, knowing size of the files would take alittle while to download. I bought them 2 days before I am to leave town. Now, I'm just out the $50 and won't have anything to watch on my flight!
