You can download it, just keep trying. – Back to the Future: The Game Review

Amazing game and gameplay totally worth it! Episodes 2-5 will download, it took me around a day and a half to figure it out but just keep trying. Ironically episode two finished downloading as my re-re-re-re...watch of back to the future (bttf) finished. Game is great and the story for all the episodes are great.
