Directory Finding Problems

[grillder 0]

Ok, so I've not played Chernarus DayZ in a while (Mainly Celle and Namalsk) and today I decided to play it. So I opened DayZ commander and it said that it couldn't find one of my directories for ArmA 2 or ArmA 2 OA. So I went into settings and overrode so it could find them, then apparently my ArmA 2 was out of date. I just went to update it and it just pops up with an error saying "Wrong CD Key."

I know exactly what this means and I've never tried to hack in my life, what could this mean? I've verified my game caches and reinstalled both games but it just continues to say I have a wrong CD key. Any help?
