It´s absolutly what i´ve done.
I´ve installed the game several times, applied the patch all went o.k. like you said. Applied the patch meanwhile several patches but same result as every time an error message when you double-click the icon or run the game out of the start folder or something!!!
I´ve no clue what to do perhaps, the game i´sn´t working but I´ve tried it with another game!
Perhaps somebody knows another possibility to try!!!
