Assuming this is for Combat Arms Classic.
The game must be ran without BattlEye enabled:
Make a "Start.bat" file in the game directory with the following contents:
"Engine.exe" -windowtitle "Combat_Arms" -rez Engine.REZ -rez Game --lc=EN -BattlEye 1
This is temporary, I am working on a loader that works with battleye.
for now, this is the only way to use the hack and thats why its so cheap - 10 cents a day!!
