ArmA 2(Steam) + OA(Retail) patching error

[SAYSteez]

Hi, I just installed ArmA 2 via steam and I installed my ArmA 2 OA via DVD which auto installs into the ArmA 2 steam folder. My problem is that when I try to patch ArmA 2 and OA(CO) with the ARMA2OACORFT_Update_160 it gives me an error saying "Error found in file EXPANSION\ADDONS\wheeled_e.pbo" and if I click 'Ignore' it just gives me an error with another .pbo file.

I ran ArmA 2 before installing OA but I can't seem to dodge this error message

Steam will auto update the patch, you dont patch steam copies like other digital copy or CD copies.

Try getting the OA only patch for the OA cd copy that you have. or try to use your cd serial key and add it into steam if it accepts it you can have full steam copy.

Hi, first I would like to say that there is no standalone OA patch; they're OA+CO+RFT. Second BIS doesn't allow you to add your retail keys to steam as it doesn't work.

Sometimes installs from DVD produce corrupt files and then patches fail to complete.
Try copying the contents of the DVD to a temporary drive and then run setup from there.
(You might need to uninstall the old Arma2 OA first).
After completion of setup run once Arma2 OA and then patch it.

That didn't work either :\

So is there a number I can call? I posted this on the steam forums and got no reply on how to fix it aswell.. Doesn't seem like anyone knows how to fix many things in these forums just by looking at the other threads with no replies..
