I couldn't get it to work for a while but here's how i did it..
-Run Macro as Administrator
-Press "Enable" and On"
-Run AvA (I did it in windowed mode and it worked for me)
-Set your shoot button to the mouse wheel
-While in the lobby left click and monitor your Macro (If in windowed mode)
-If the status changes from a red "OFF" to a green "ON" whenever you click you're good to go!
I know it seems pretty simple but i had problems with it : ( and i just hope this helps you guys out!
