This is happening to me too. I'm reinstalling to see if that fixes anything.
So did it fix anything? My 1.4.6 still freezes the second I try to move someone in or take control of a household. Have to play without awesomemod
It took 3 times to get it right. First time, my sims kept getting stuck in the mailboxes right when I started a game. Second time, every time I tried to choose a family it would get stuck in the neighborhood view, but the third time every thing worked fine. I have no idea why it would take 3 installs for it to work, and maybe that wasn't it at all that fixed it, but its working now so I'm good.
