The first time I experienced the strange screen on an update was update 12. At that time I did the uninstall/install and the problem was solved.
From that time all of the following updates have been successful with no need to uninstall/install.
History: the first time I ever used gameguru I unchecked the box in the welcome to gameguru screen so I would never need to see this screen again.
After my problem update 12 I have never un- checked this box I just close it and then the gameguru editor loads and runs on all following updates.
My thought process here is why are only some users getting the update crash and not everyone. Could it be only those who have un-checked the welcome screen are effected? Sounds silly but the missing portion of the editor when the editor crashes on updates bears a strange resemblance to the missing welcome screen.
