I have tried the two last mega trainers.
When I press F1. It starts with ONOFONOFONOFONOFONOF until I kill the trainer. If I continue. The game quits out too windows.
My game is from ORIGIN..
There's your problem. "May not work with all versions". Origin wasn't even around when the trainer was made.
I agree that Origin wasn't there when the trainer was made, but there is still a possibility that the trainer might work, seeing the latest build still is 1.30 (Beta).
So make sure you read the troubleshooting guide I have linked you to, just to make sure nothing else is responsible for the infinite sound loop.
