I was using the Yuuutu engine and editing the SetGlobalOption (to make my room show up instead of the engine's) and I broke the engine. I'm not sure what I did, but the engine brings up this whenever I try to start the game:
___________________________________________
FATAL ERROR in
action number 1
of Step Event
for object init:
Unexisting room number: 0
Looking at the text there is a slim red bar, which I think means the code is broken, although it could just be there for effect.
If anyone knows how to fix this, that would be great.

The unexisting room number means you're somewhere in the code you're entering a room that doesn't actually exists, resulting in a forced abort since you obviously can't enter something that isn't there.
If the only thing you were messing with was the SetGlobalOption script I suggest getting the original script and seeing what's changed and change back what you were doing one by one and figure out where the problem originated.
I never saw that script when working with yuutu. I probably just have an older version.
Edit: My guess is there is a room being referenced in the init object's step event which you had renamed or deleted.
Edit2: The slim red bar (extremely faint) is the section your cursor is located, not an error.
Errors in code occur at the bottom like this: Mine looks different because I changed how it looks in preferences.
