I know I said I will be gone for a while, but I cant leave without fixing bugs in this .

Dj Tech42, the error your getting is in a validity check I have. For every game there is a default value automatically saved upon every save that must equal "valid", under the name "__default" (please don't use any names with double underscores at the start when saving, they are reserved for use by the internal workings of the tool, I should have said that in the main post, but that is not the problem here anyway).
What I should have noticed in the code is that when that value does not exist there will be an error when the code tries to get it.

I've fixed it by adding my friendly dict class (a class that emulates a python dictionary, but does not throw horrible errors) that I built for Addons.

I've updated the top post with the new version.
I hope no more bugs come up, bye for a while.
