Might and Magic 7 Resolution problem

Hi, I'm having trouble starting the game..
After i start it, I get an error saying "To run this application, the resolution of the screen should not be less than 800x600"..
I have done all things nessesary to run in XP.. Changing compatibility and downloaded the latest patch (v1.2).
I don't know what it is, if its my widescreen, my graph gforce 8600 GT or dualcore.. Please help me, i love this game to much :p

To avoid dupication of answers.

Try selecting "Run in 640x480 screen resolution" from the Compatibility tab.
