game keeps freezing at the same Sim-time

Hi!

So, I just installed TS3 and all of it's expansions two nights ago (but none of the stuff packs) onto my computer, which exceeds the minimum system requirements by a lot.  The first night of playing, I made a fresh town and played for several hours (over a week in-game), until the game froze and would not un-freeze (this was in Moonlight Falls).  I had just saved, so I didn't consider it a big issue.  But when I booted up the game the next day, it kept freezing when 7:30am rolled around for my Sims.

I have some CC (some .package, some store content, all of which was previously checked with Delphy's Dashboard), and I used a mod to pack up my family and pull them out of the game.  Tonight, I deleted that save and started another fresh game, then dropped my family into the new save (in Isla Paradiso).  

That seemed to help, except for some minor freezes which I took to be the result of putting them on a houseboat and having to render the waves, etc, all the time.  So I used the Move option in-game to send them to a new home.  They arrived and finished moving at about 12:30am in-game.  Now, every time the game gets to 2:30am, it freezes all over again, and I have to pull up the Windows Task Manager to force close it.

Am I ever going to actually be able to play this game?
