I'm having trouble getting my retail copies of Arma 2 and Arma 2 OA registered on steam. Specifically to play DayZ Mod if that matters.
Basically, the situation is I initially bought Arma 2 CO on steam, and all was good, but due to an irrelevant series of events, I ended up with different CD Keys that had a battleye ban on them.
So, I went and bought a retail copy of the game, installed it separate from steam, and all was good again. Now Gamespy stopped supporting matchmaking, making a retail copy not useable for multiplayer. I read through the update and saw that I should be able to register the retail copy using my CD keys as a product code.
Then here's the problem. When I attempt to register them, it just says it's not valid. I'm assuming this is due to the fact that I already "own" the game on steam. I also tried making a 2nd account on steam, but same issue and all the games I own on my main account are grayed out with a prompt to request to borrow or buy a copy off the store.
And I have of course tried the usual reinstall, verify game cache, and I wasn't able to locate the steam CD keys in the registry, just the retail ones.
Now, does anyone know if there's a simple fix for this, or if there's a way to change the CD key on steam? Or it is really just a matter of buying another steam copy on the other account? I'm well enough within my means to do so, but I'd prefer to just be able to move it over as intended.
