It seems that a lot of players who launch Dayz Overpoch with Dayz Commander have been having problems doing so recently due to the chaos relating to the shutting down of Gamespy and Bohemia's switch to SteamWorks. I've found that using Arma II launcher to launch Overpoch is now the best method. Here's a simple guide for anyone having trouble setting up Arma II Launcher for Overpoch: http://dayztipz.com/Overpoch-Launch-Guide.html If you're looking for an Overpoch server to play on, check out EGC Overpoch Chernarus.
