Error Message!

[Eienchi]

I've only gotten this error message a few times. It pauses the game, I hit reset. It fixes.
But now it keeps happening everytime this person has their First Kiss video. It pauses it during the video, a box shows up but i can't click reset. And i can't keep playing. So everytime She tries and has a first kiss it dies.

Thats the box. I'd like to know how to fix it.
Can someone also tell me whats glitching?

Are you using boolprop or a debug?  

[Menaceman]

These errors should only show if you have testingCheatsEnabled turned on which puts the game in debug mode.

Turn debug mode off and then try having your Sim get thier first kiss. The error shouldn't show and the game should just play through it.

Just like everyone else said.

All I have to add is that whenever you see such an error message,
ALWAYS press Reset.
