Game installations and updates hang endlessly just before finishing. They will download/install just fine until it gets to the last couple mbs, then will pause and act like it is still working. I have left it for hours once and it never finishes. Pausing it and resuming seems to make it think it’s done, but I have read even this is considered an interruption that results in missing files that have not actually downloaded/installed. This is quite believable, considering the fact that almost every Modern Warfare update results in the game not working.
