SIMS 2 LEGACY COLLECTION NO NEIGHBOURHOODS / CRASHING?

Hi, I've been trying to work this out for ages. I refunded it on EA and got it on Steam instead. I go to load the Sims 2 Legacy Collection. It tells me I'm on low disk space which is far from the truth as I have PLENTY.

Then I load up the game and suddenly there's no neighbourhoods? I don't see any templates either for creating them and trying to load into the tutorial as well just causes my game to crash.

Has anyone come up with a fix? I spent $50 AUD.. TWICE! Waiting for my refund so $100 is gone. :/
I'd really like to play this weekend before I'm back on Monday - Friday shifts.
