I have had DayZ mod up and running on this machine before but had to uninstall due to space issues, anyways... I followed the instructions and here is what happened: Installed ARMA 2 and ARMA 2 OA ( I have NON Steam versions I bought/downloaded from Amazon ) Patched to 1.11 and 1.62, Started ARMA 2 and ARMA 2 OA ( would get a black screen with just sound sometimes ) one time each before as specified. Opened DayZ commander and updated/installed the mod and says everything is up to date but when I go to join a server i get the "system cannot find the file" crap. I opened the settings in commander and all the correct directories are there and spelled right etc. Tried latest Beta patch for ARMA 2 and repeated process with same results I have searched forums and did not find any solutions to my issues. If anyone could help I would appreciate it, I had this game up and running a few months ago so I know it works but I cant get around these issues. Thanks in advance for any help.
