Drop the whole trainer folder in C:\
Run the trainer as Administrator (I do this even though I'm running XP.)
Run Vindictus
Launch a private board.
Enter the first level
Press Ctrl+Q (For some reason, the hotkeys work for me, but the buttons don't)
If you still can't get it to work, you're either following the steps wrong, or you're just not going to be able to get this to work.
