FWIW...I had a similar problem with the first updated AwesomeMod after patch 1.3!
Running a legit game, fully patched to 1.3, with just the AwesomeMod and an xml tweak (the gymbufffixed package by DilPill)...after the intro video, the game screen went black and would hang! I still had the little whirling cursor, but the game wouldn't load!
I manually shut down the game, deleted all of the cache files in My Docs/Electronic Arts/Sims 3, installed the updated enablescripterror package from MTS...and the game loaded fine! I don't know if it was the cache files or the enablescripterror.package or just voodoo, but my game has not crashed/stalled/glitched since!
