@Libersim A dxdiag is a type of report on your system that lists a lot of possibly relevant info: driver versions and dates, Windows error reports, plus most of the hardware. The idea is to look for obvious problems and address them, then see whether the app works.
Having said that, you may have better luck on the (still very new) official EA forums. Some players there actively use CAW and may be able to help walk you through the troubleshooting process. I'd post in Sims 3 General Discussion since that's where most players are looking.
