This is a problem with steam (I think). I didn't play it for like a month, then when i went to play it, it just stopped working. I did the "Verify integrity of the game cache" and it still didn't work. I noticed that it said "Fragmentation: unknown." I clicked on defrag and it said that i should run a whole system defrag, I did, but it still wouldn't work. Then i decided I would "delete local content" and when I did that it said, "You don not have enough disk space to run this game." What? I'm deleting it, how do i not have room to delete it? It still went to NOT INSTALLED. Then when i tried to re-download it, it said the steam servers where busy, I have proved this wrong by downloading other stuff. I deleted all the program files for it too. HELP!
