Do you have Vista?
Try running as Admin
Right click on icon-->Run as admin

Alright I got it.
I just experienced your problem and i solved it.
Here's the solution:
C://Program files/Diabulus PKO/Diabulus PKO.exe(shortcut)
Open that and you'll be able to enter the game.
I tried it and it works so goodluck to you.
