Overpoch won't load... Please help.

[JayCoops 0]

After wiping my system and re-installing Arma for the fifth time since this whole Steam patch, GameSpy mess. I have finally made some progress in getting DayZ working again. However, I can't play anything that requires more than one mod (such as Overpoch). I can only go into Epoch, Namalsk, Taviana etc singly. Overpoch or Epoch on Taviana for example, I just get thrown straight to the main screen. Has anyone had this before or know how to fix this?

 

Any help will be greatly appreciated.

What are you using to try and join, DayZ Commander or DayZ Launcher?
