I'm able to get the game to boot in vanilla. I'm crashing when I go from ESRB screen to game instance after using Windower 4 GUI.
Same problem for me. I can load POL through Windower4 just fine, but POL crashes after the ESRB screen. Can load the game just fine if I go through regular POL without using windower. Have tried checking and unchecking compatibility modes for everything, checking and unchecking run as admin for everything... nothing seems to work.
