Have you ran the trainer in administrator mode? If you right click on the file, select run as admin. This may help as I was having problems until I did that.
Tried that, didn't seem to do any good. I've downloaded the key-customiser tool and tried using it, but I have to say it's one of the least user-friendly programs I've ever seen.
Edit: Never mind, I got it. Run as admin worked, just forgot I needed the "fn" key as well.
