just posting to say i'm in the same boat as you guys. i was playing just fine until this update and now, wtf? i never needed the installer/beta.exe until now and even then, they don't work properly and i'm 100% certain that every setting is filled out correctly. i've even re-downloaded copies of ArmA II and O.A. from steam as well as re-downloaded the mod files, nothing. the weird thing is sometimes i can get it to run without it blurting out the "CABuildingParts' error but then i get a new one: "The Version of ArmA2 OA (9.20) is more recent than this patch version (1.60)." now, what.the.fuck!!! :huh: i'm just a little miffed cause i've never had this amount of trouble modding any sort of PC game. are there any forum mods/admins that can speak on this?
