I keep getting this error

[jennietee]

I'm a relative newbie to creating games here and I've looked all the over the place but I can't seem to see why would be getting this error. It appears occasionally when I play test my game, causes it to crash and then I can't access that save file. Thanks for any help.

Two questions...
Is this the unmodifeied kit?
and
Are you using the patched version, 16.2?

I've edited some of the sprites but none of the code or anything.
I am using the patched 16.2 version.
