Eyme you have 4GB you should not experience a crash it is those with over 4GB of memory.
Well, I do have problems! I think it was a bug in the AM because when I deleted it, my computer started working. I think I'll just wait until they update AM again and fix the bugs.
I would suggest that anyone running 64bit Windows with more than 3GB of RAM go ahead and set the IMAGE_FILE_LARGE_ADDRESS_AWARE flag in the application, particularly if they are having a CTD problem.
Sims 3 does not seem to use more than 2GB of RAM, whether that flag is set or not, but setting it does not do harm and may correct compatibility issues because Windows 64bit handles memory above 3GB differently than Windows 32bit.
Okay, I'll try that.
