Extract the .dll hack you want to inject to your desktop. Make sure PerX is there as well. Where it says "What to inject:", type "AVA" (without quotation marks). Where it says "How to inject", select "Manually". Where it says "Add to injection list" click "Browse", then navigate to the .dll and open it in PerX. Start AVA. Wait until you are in the lobby and then press "Inject" in PerX.
Closed.
