Don't forget to delete the cash files (4 of them) in you My Documents-Electric arts-Sims 3 folder.
I've also found the inteen, gainskills, potty train toddlers, leave baby alone, and coworkers speedups mods conflict big time.

Patched from 1.4 to 1.7 vers 2, (pain) because I had to get the original videocamera.ini file because the videocamera file I had was altered. the correct file should only be 1.63k. Get it off the disc or hunt for it, someone on the web might have it.
Save, then remove the "Mod" folder from the framework.  The mods that don't seem to conflict are the hairy body and skin textures and tones,  some skill speed ups, and most of the actual mesh items.
What causes the hang ups and bugs are awsomemod 1.7 beta (game runs slowly) and inteen(any version.)
Sucks because Awsomemod with Indiestone was so cool and made the game playable and fun. Inteen I can live without, never used it anyway.
I don't know if EA is trying to f**k up this game by roadblocking the modders or if the game is sloppily programmed that internal tweaks by EA makes the game delicately unstable.
The Awsomemod 1.7 beta does work, but not well as of now. I gotta hand it to Pescadero for making the awsomemod to begin with, pure genius. I'm not sucking up by saying that.
