Sorry, i dont have a solution at all, but i get this error too when in installed OA from DVD. I just copied all the files from the DVD to a new folder. After running the exe on my pc without the DVD it works for me.
Maybe you get the OA DVD from a friend (Dont forget to use your own key )

AND clean your registry !

There were quite a few occasions when the CRC check error was down to a hard drive problems. You should be able to get an HDD check tool from the manufacturer's website.

the versions i am using are

Arma2 DLC German version by Morphicon
Arrowhead DLC Sprocket
British DLC Sprocket

I hope this helps at this time the only way i can play is

Arma2 on my c:drive
and Arrowhead dlc british om my d:drive is there a way to make a short cut that would load both up at same time to make it into combined ops
