I have had this problem every since I first instaled WA. I did a fresh intall of Windows 7  and Sims 3 and WA. on a secondary boot and still had the same CTD at random. So after Awesome Mod was updated for it I installed it and still had random CTD with no other content loaded other than Riverview. But after switching to Awesome Story Mode I have not had a CTD in 2 days. I am not sure if it is sometthing inthe EA story mode or not but i would like to Thank J. M. Pescado for all his hard work on trying to fix EA bugs!!!!!!
