When you try to download a movie or other type of video using iTunes you may encounter error 8008. This is reported often when you have a series of video content like multiple episodes of a TV show. You may get 1/2 way through your show and encounter the itunes error 8008. The solution to this error seems to be to locate the partially downloaded content and delete it from the tempoary downloads folder. This causes iTunes to re-download the show or movie and yes you start over but you don’t get the itunes error 8008.

So check out this path as yours will be similar. C:\Users\Administrator\Music\iTunes\iTunes Music\Downloads
What you want is to locate your “Downloads” folder which is where iTunes stores movies and videos you have downloaded. You need to find the show you cannot download without error 8008 and delete it. Then try and re-watch the TV show or movie and you should be able to download without seeing iTunes error 8008.
