I just bought GTA IV on the Xbox Live market place in the ''On demand'' section. Everything was fine until i enter the game and get the ''Disk is unreadable'' error message. The thing is since it is a digital copy of the game i don't have a CD so i don't get it. I cleared my cache then reboot my xbox and it's still giving me the same error. I don't know if the file is corrupt and i need do redownload it but if it's the case i'll do that tomorrow.
I just wanted to know if there is something i can do to fix the issue before re-downloading a 6.51gb file.
