Disc read error on downloaded game?!

I recently purchased Bully Scholarship edition since it was dirt cheap and I really enjoy the game. I got to the Dean's office for the first time and the game froze with the error "disc read error: please close tray or clean disc." I rebooted my system and
tried the game again, this time it didn't make it through the opening cinematic before getting the same error! Ummm, I'm no rocket scientist, but when a game is downloaded, you don't have/need a disc! I have cleared out its data and re-downloaded it to get
the same result over and over. Any ideas?

Disc read error on downloaded game.

I downloaded Ninja Gaiden Black and started to play only to find that I got a disc read error before the opening cutscene ended. Obviously there's no problem with the disc, as there is no disc. I've already deleted the game and re-downloaded it to no avail.
Any suggestions? Would support give me my points back if this doesn't work?

This console is just a pain in the butt to deal with. So many problems...

 

Delete your profile and the digital game from the console and clear your console cache three times in a row:

support.xbox.com/.../clear-system-cache

After this download your profile again in the console and and your digital game from the download history.
