Now when I launch Reaper it says "ERROR #121 (0x85100079) Version Mismatch" "DBFilesClient\AnimationData.dbc has wrong row size (found 24, expected 32)" And it crashes my monitor till' I ctrl+alt+delete and open the task manager. When I try to click on the dialogue box to hit ok, my mouse cursor completely disappears... WTF kind of madness is this?

I have Cataclysm, but accidentally ticked the WotLK box in my acct. creation. How do I change the expansion? I suspect this is why I am instantly kicked off the server at login. I also am patched to 4.3... Is that why maybe? Someone help?
