Stencyl Beta 3 can't change game settings

hey, i have just upgraded to the newest beta of stencyl, and when i try to access the game settings of one of my games it produces an error and generates logs.

i have attached the logs, can anyone tell me if it's something in stencyl, or maybe my game?
also is there another way i can access my settings? i want to change the display size of a game.

thanks in advance

i also can't close a game with out getting an error.

It seems one of your extensions is outdated and causing problems. Try uninstalling it, save and exit, and try changing your game settings.

thanks, is there a way to make it work afterwards or does that mean the extention can't work anymore?

Based on your logs on guessing your using this extension :

If you want to continue using the extension , create a post there saying that the extension is outdated and make a request for a fix.

thanks, i know what extention causes that, it's the only one i have installed. i have contacted the creators in hope for a newer version, but i also looked for alternatives.

just in case anyone is wondering, we're working on an RPG game, and the extention is the Easy RPG Creation Kit, but it might be too outdated to work.
