Nba 2k10 disc problem(unreadable)?

Alright so it tells me i have to turn off the console/reset it and clean it with a soft cloth. The disc had no scratches anyway but i still did it. And when I did it it still had the same problem. I tried resetting the cache of my xbox and still no help. I removed the hardware to see if the files were corrupted but they weren't. Every game I own works but NBA 2k10. The game was working for a day and than all of a sudden it stopped working.
