Determined

The command prompt comes up and says this: C:\Users\Bobby\Desktop\arma2>C:\Program Files (x86)\Bohemia Interactive\ArmA 2 O peration Arrowhead DEMO "-mod=@DayZ" 'C:\Program' is not recognized as an internal or external command, operable program or batch file. C:\Users\Bobby\Desktop\arma2>pause Press any key to continue . . .

I don't know what a .bat file is. I've run and played OA by itself and it runs just fine.

First I get the message "Addon 'Takistain' requires addon 'CA_E'" then after it fails to load it gives me an error message saying "Bad serial number given in Setup" FYI, Im using the Six Launcher and I do not use Steam.
