Hi johnlax first things first GWE ? do you mean GWX3 if so
have you installed the 4gig patch and also the Commander Config patch for
GWX.
Also starting a Career off the bat in 1943 with the Commander Mod causes crashes from my experience but theres a work around start a campaign two years before say Jan-March 1941 then just go out on a shake down cruise for 24-48hrs around the bay of Biscay then return to base dock at your home port and come out of game.
Then fire Commander mod back up alter days in port between patrols to 730 days as in two years restart your game though the Commander mod and bang your in you Uboat in the Channel coast ports Lorient Bordeaux of your Flotilla ect in 1943.
Thats how we did it at the Steel Sharks Clan when ones Computer takes a dump and you have lost your Campaign files ect and you have to restart your campaign from say Jan-1943.
