Hello, I've recently installed all of my Armas to play the DayZ Mod again. I have a ran into a problem that I've had before and it's very annoying. I open up DayZ Commander and try to update to the latest patch for ARMA 2, but it says "WRONG CD KEY". So it won't actually install the patch even though it said it did. My Armas work perfectly fine in Steam, and I just want to play the DayZ Mod again. If anyone could help me out, I'd appreciate it.
