Well, first of all. The inject button is an auto inject. It has a check to see if the process is running, if so then it injects the dll. Otherwise, if the process isnt running, it will still start the injection thread and WAIT for the process.
As for closing on injection, there is an option in the settings, which I advise you to look at. It is a one time config only.
Ok can i get some instructions on how to make sure i get the hack to work damn im an idiot
