It only the F3 (exp) dosnt work!!
Teamviewer is a remote control software that allows me to see your screen and the things you do and if you agree I can take over control. It's helpful because I can see how you use the trainer and I can also take a look at your game's memory I am not able otherwise which makes it impossible to see if the trainer works the same as on my end.
