I think I posted this in another topic but still It might help some.
Windows has a function called compatability mode. This allows you to run files as if you were on an older operating system.
I've noticed that many people have had problems with Vista and this is what I did to make it run on my Vista Comp. Right click GE then click the compatability mode tab. Click the box that says "Run this program in compatibility mode for:" then click the drop down menu and select Xp. Since I have done this I have had 0, Zilch, Nada, problems. I just thought I would let others know.
