que3 0 Posted July 27, 1999 The interface screen in F4 freezes shortly after appearing when im using the PERMEDIA2(MS) driver. When i load the most up to date 3dlabs permedia2 driver for NT4 the game runs fine but at the end of any mission (TE & Campaign) it crashes before reaching the debrief with the following error: [setCooperativeLevel (exclusive) failed] Error: 433 C:\mpr\ddk\eng\esurface.c MAR 17 1999 Has anyone else had success or failure with F4 in NT2K?
