I have 2 systems as of yesterday and one is my brothers. On mine I had the 2k13 demo and I downloaded that ... then I went and downloaded the full game... I use my account on his system and try to re-download 2k13 and it just stops downloading at 87%! I have plenty of free space, theres nothing on the system yet! The download continues to say DOWNLOADING but never passes 87%.. Is it possible that I would need to download the demo again on the new system and then the full game?? Could that missing percentage have been bc I had it from the demo????
