I own: TS2, S2U, Nightlife, Pets, Holiday party pack, family fun stuff.

I have successfully installed and updated TS2 and S2U (Haven't installed other exp packs yet). I load the game. However, it crashes immediately after the introduction video has ended. I have tried with a different expansion (Pets (without University installed)) and the problem persists.
