Still found nothing to help, might just have to redo Episode 3 and HOPE it works this time.
P.S. Seriously TellTale why when using the ingame downloader for getting new episodes is ALL the data being saved in the Documents folder. This presents all sorts of problems for backups and people who use multiple drives. These are common complaints whenever a game is released with this sort of data handling. I would of thought your developers would actually think such things through. It is also different to how Steam is handling the files... Why didn't you just stick to 1 method!
