Exception Error #1010: A term is undefined and has no properties

[JohanDegraeve]

This is 1.0.7. using Flash Builder
Went to advanced settings, changed to "agresssive"

then clicked back (i think)
then exception occurred;

black screen shown, even after restarting.
It looks I have to reinstall the app
