Alright, here's my method.
Listen carefully.
1. Open the hack. Make sure you run as admin.
Also, right click your hack, then go to properties, compatibility tab, then tick the run in compatibility mode for Windows Service Pack 2.
2. Open Combat Arms.
Get ready to press Start then press enter.
Make sure your computer is focused on the hack.
3. After that, it should load and all.
You will get an error saying something about Engine.exe.
Click the black spot and let CombatArms load.
Then either click the error or alt+tab out of game.
Make sure you don't click OK on the error!
Now drag it to the bottom corner or somewhere.
Then play.
You SHOULD have chams.
NOTE: Don't delete any HS folders or anything like that brotha.
Thank me if helped.
