Okay so I was trying to make a gamebook thing but It won't let me and always says "Sorry, an error occurred while processing your request." And was wondering if anyone knew how to fix this or even just what might be wrong?

Does it happen while tinkering in the program after opening it up or does it do it on start up?

If it’s on start up... uninstall and reinstall. If it’s while running the program, give us more info.
