I am the person in question like STK said.
I have the steam version where it says ArmA2 and ArmA2 Operation Arrowhead.
I got SixUpdater installed along with Addonsync but still no result.
What do i need to do to get Acre and JayArma2Lib working??
It's difficuilt to explain here what it all says but i can't be that hard to install it on the steam version.
