I am getting the same error message while pressing F1 and it is not working at all and yes I did everything and everything is enabled DLC side too so why is it not working at all?
Same message as who???? Post your error message so we don't have to go hunting and guessing.
Delete trainer and all files in

Reboot PC to clear excess memory, get a fresh copy of latest trainer and extract it. Run trainer as admin, read the instructions and try again. At times, a new game may be needed to resolve failed options if the data in your save file was altered. Use on a new game and test the option. If it now works, quit to main menu and load your save and try it again. May also need to run the game without the trainer first and play a bit so the save file gets updated to use possible new values.
I don't get it - how can this make some options work properly? The trainer functions - just not as before thats all.
