Okay, I just went to go and play the unmodded new 4.09, and uh...how do you get back to it. Oops!
Well, you use the switcher to bring it to unmodded 4.08, and then run the 4.09 exe. again, and it brings it right back.
I'm going to do it this way until the AAA team come out with a new a switcher. I really don't want a dual install! The 4.09 exe. takes only a few seconds to run.
But, the good news, still, is that it doesn't screw up your AAA mods.
