I have win 2k based system, with duron 700 and 126megs of ram. I also have polish version on ofp, after some time playing about 5 min the game crushes and switches restes the system. I tried to install patech from this site but they changed the language of the game from polish to czech. I would like to know how to overcome the trouble with crushing game, and how to install the patechs and still have polish instead of czech as the game language
