Sims 2 Ultimate Collection suddenly crashing?

I just recently downloaded TS2UC and was able to play only a couple of hours on 2 consecutive day. Third day it refused to load at all. I watched it on Task Manager and it would begin to load and then the process would disappear. I contacted EA Help and after talking with a number of different techs I found a fix on the Headquarters Help site which required using regedit. That fixed it temporarily but a couple of days later it again refused to load. This time I deleted the 2 cache files. It loaded. Has happened a couple more times. Usually after I have added something to the User files like new Downloads or lots. Don't know if deleting the cache files would help in your case or not. I haven't had a crash after actually getting into the game.
