yes i have tried that, they say that the key doesnt exist

I'm trying to play wasteland, i have been playing Dayz for weeks, (please note getting that to originally worked was extremely difficult but it magically decided to work one day.) Any way wasteland wouldn't work when i tried to play it for the first time yesterday, so i tried completely removing Arma 2 and OA. My main problem i assume is that i bought Arma 2 from Amazon, and Operation Arrowhead from steam. So i just removed Arma 2 again because it refused to run by itself (Failed Serial number or somethign along those lines), after i already started it up a couple of times just fine. Im going to install it again, but where should i install it to? and would it matter? please note it is NOT bought through steam, but OA is. The issues ive been getting are: a10.pbo, aircraft.pbo etc... wrong signature errors you cannot play/ edit this mission a.Chernarus a.weapons etc... has been removed errors It also doesnt have the Arma 2 symbol in the bottom left when i start it up, but it pops up in expansions along with some expansion called "ca" What should i do? ive tried the copy addons folder trick to Arma 2 oa. and that originally fixed my dayz problem, at this point right now i dont even care about wasteland but just dayz. i need a list of all my possible options. please! im getting ready to install Arma 2 again to fix serial number error, OA is still on my comp. need fast response! Location of both originally: D:\Programs\steamapps\common\Arma 2 Operation Arrowhead D:\Programs\Arma 2
