Nintendo Wii Disc Help?

I have a Nintendo Wii and recently bought "Gravity". The Wii is trying to read the disc but then all I get is an error stating "An error has occurred. Press the Eject button and remove the disc, then turn Wii console off and refer to the Wii Operations Manual for help troubleshooting"

The disc is extremely clean and is not likely to be the problem.

The Wii is also able to read all my other games just not this one specifically.

Anyone have any ideas why?

Suggestion:

Check the wii system memory for a "Gravity" game save file, and try to move it to an SD card. If you don't have an SD card then delete it, it's probably corrupted, and the reason you're getting an error message. Then try starting the game (with no save file in Wii system memory). If the game works it was the corrupted file (this happens sometimes). If not, then the problem is probably the disc (flaw in the programming, not a flaw on the disc, maybe). If you can try the disc on another Wii, that will tell you for sure whether it's the disc or not. If the disc then get it replaced, or get a new one.
