Until now i think.Let me try to simplify all of your problems, HakkinenF1.
1) To activating this feature, click "enable" in the checkbox.
2) Make a change to XYZ values. If you're not sure this is work, try set bigger value such as 20.00.
3) Press "apply" button (next to "Close" button) when all changes has been done.
4) Run GP4. If nothing happen, quit the game and check a file called "gp4tweak.log" stored in your main GP4 directory.
5) You may posting the content of gp4tweak.log here. No credit-cards information will be posted.
