Hi!
I got it!
Now Lockon is working nice! Just uninstalled nvidia recent drivers and went back to my old 61.72 WHQL drivers and it starts to work fine. No problens till now! (Full screen 1024x768) - settings gone to medium, no water, and full hardware aceleration.
Well, now I will start to have real problens. Like: Not being shot.
Thanks again!
Oskar
