Sims 2 Open for Business Problem!!!(no nocd)

[grm¸]

right... I also have a problem, so if someone could please help me, I'd be pretty damn grateful, since I'm starting to lose my patience.

I have The Sims 2 installed on my machine. recently I bought the University expansion pack, installed it and it worked fine. then I got Nightlife, installed that one as well, and it worked fine (both of them were installed).

Then I got "Open for business". I installed it. Everything seemed ok at the moment. I copied the crack file to the folder (C:/Program Files/EA Games/The Sims 2 Open for business), and there wasn't the usual "would you like to replace..." screen. It just got pasted. there was no appliaction, and the file with the same name (Sims2EP3) was just an icon (image).

And, of course, the game doesen't work.

So. what's my problem and can someone of you beautiful pople help me please?
