im having quite a few technical difficulties, so anyone that is reading this, if you could lend me a helping hand i'd really appreciate it: im getting a lot of error messages ("invalid constant", etc.) with my sim that i have living downtown. it was her and 2 other sims, i tried moving the two that were getting the most error messages out, but they wouldn't leave, after several attempts to reset the problem, i deleted them using the prompt options ( cancel reset delete) but that didn't work either. also, i went out on the town with her and i kept getting an "invalid constant" error message with a few of the sims there and when i deleted one, there was an issue with another one. i deleted that family completely, started a new family with just one sim, and the same thing happened. i thought it was the cc so i didnt use any, but it happened again, and when i sent her 2 work in her car she came back in a carpool, the car was gone, and i couldnt get a new one. also, i couldn't ask the gypsy for a date. the first family i played didn't live downtown and didnt use cc except the clothes, and i didnt have a problem with her until today (i installed nightlife yesterday). i noticed that the error messages pop up when i hover over another sim. reset isn't working at all, and delete doesn't seem to be doing much either. some things to consider are: i'm using boolprop testingcheatsenabled true, and i haven't installed the patch yet because the computer i sim with isn't hooked up to the internet, and i think i have the university version of inteenimater. i don't know what to do. should i delete inteenimater? reinstall nightlife? please help, i'm pulling my hair out

Two things:

Do not use boolprop testingcheatsenabled true all the time when playing, error message are going to pop up that don't always mean anything.

Definitely get a newer version of InTeenimator that's compatible with your EPs, the InTeenimator is a hack that can cause major problems if you're using the wrong version.
