Diablo keeps quitting out with this error:

Diablo III was unable to validate core data files.

It tells me to use this ID code when reporting this issue, but I don't know where to report this code.

The Battle.net site will not accept Diablo 3 errors.

The codes are used to identify the crash info you submitted. In looking up your code, I see it's likely due to corrupted cache data.

Delete the following folder.\Diablo III\Data_D3\PC\MPQs\Cache first, then run the repair tool in the launcher. You access that under the Help tab across the top of the launcher. It can take a while to run as it rebuilds the deleted info so please be patient and let it finish.
