# Verhext :
help! i have exactly the same problem as stated earlier, i have Arma II + OA (combined operations) from STEAM, and everything is up to date (through steam) , my armaII.exe version reads: v184.108.40.2060
Start CO, not A2. Seeing how you refer to the A2 version number I guess you are not activating CO?
I am not familiar with Arma and Steam (and hope to never be), so maybe I say something stupid but you might want to be sure you are actually running both.
