error with oclhashcat-plus64

it doesn't look like you are using catalyst 12.8 as you claim, it definitely looks like you are using catalyst 12.10. if you had previously installed a newer version of catalyst and then tried to roll back to 12.8, it's highly likely the new version did not completely uninstall itself. also keep in mind that catalyst on windows updates itself automatically.

clean out your drivers, then do a fresh install of 12.8.
