Hi guys, for some reason its not allowing me to create a thread, but this thread is kind of close to what i am struggling with. I bought ARMA 2 Complete Collection from g2a i downloaded it all etc and now it pops up with a window saying you will need to activate this product type the key in when the game asks for it, it hasnt asked for it??? i copied the key into the "activate a product on steam" and it says invalid product code?? it says i need to Activate Opperation Arrow Head and the DLC Czech it keeps saying invalid product code? due to this i cannot get on any servers.. anyone got a solution? thanks
