Feedback, Complaints or Problems

If any 1 had the same problem as i did by using the trainer customizer please help me out.
I've pressed either Shift/Ctrl/Alt for the first box but however the big box in the middle would not change the number 255 no matter what i press, and the section where u would select the file dissapears.
I turned of any possible anti virus programmes off, redownload the rar file and still nothing.

same problem here
