Now why would you want to play stock??
Firstly, roll back the Cmdr before launching another career.
If you backed up the original files in the Cmdr before applying the GWX files you could put those back in, I think that should work.
But it might be better to have 2 SH3Cmdr installs, if you want to use, say the GWX Skinpack. You could of course make a backup of the Date folder before putting the Skinpack in and swap Date folder and Cfg´s depending on the game you want to start. Maybe someone have a better idea?:hmm:
