Issue one has been solved as well, now that I found the proper folder The mission editor is right where it should be. that's two birds with one stone. As for Issue two from what Gargamel said, it isn't an issue with me but just a bug in the game (I can live with that.)
So in other words all the issues have been solved, thanks for everybody's help.
At the time of posting this GWX 3 gold is 80% complete, I'll let you know if/when everything runs smoothly. Now if I can just find that das boot mod I've seen from time to time i'll be all set.
