Thanks for the reply. Epoch is not even an option and neither is Bell 47. There are no mention of them or check boxes.

This is what I get when I click on the Arma 2:OA launcher in steam


This is the main screen


And this is what I have for expansion options. Yes there is one DayZ that is unchecked but it is the same regardless of it being checked or not.


This is a screen of DayZ Commander


I have been working on it for hours. Only thing I have not done is delete everything, I mean everything including uninstall and delete extra stuff and start over. I have updated the DayZ commander files more than once as well as running the verification for both ArmA 2 and ArmA 2 OA through Steam and DayZ Commander.
