Alright, the one time I want to play this game so I can make some house for whatever reason in the near future I have this stupid error message with the phrase "Error Code 291."  I've uninstalled all the custom content I have and tried to start it but, no, this stupid message comes up.  I uninstall and reinstall the game, it's a completely fresh install, it works ONCE, but, now, after closing it ONCE, it gives me the same message again while there is no custom content installed and like, what the fuck, I didn't do shit.  Anyone know what I should be doing?  Did it recognize the illegal shit I did with my legitimate copy of the Sims 3?  All of that "illegal stuff" is uninstalled, by the way.
 
In short, what do I do to stop this error code (291)?
