yeah I'm getting the problem too. I'm on Windows 8.1. It loads up to the movie screen just fine and then get to the Sims Fun with Pets and it totally locks up. So I'll press my start button to go to Metro to close it out or something and then the game pointer stays on the screen like the game is still on. I'll get task manager going and because the mouse won't switch over I can't get it to end task. The only way I can close windows or anything is to go in to the task bar and right click on icons to tell it to close it and it works for everything but the Sims 2 (but when I right click on sims instead of Sims Fun with Pets it says Mansions and Gardens or something like that). I tell it to close window and then the little hover over screen flashes like its going to bring the game back in to full screen but nothing else happens. And eventually either when I get task manager up or after I've flipped from Metro side to desktop side a part of the left side of my screen goes blue like the background of the load screen for the game while a small portion of the right screen stays as my desktop kind of like I've put everything in to those snap sections. If I have my programs all set on the right side of the screen I can move them around and use them but if they were on the left side when the blue shows up, I can't get to it. The only way I can get the game to shut down is doing the hard shut down of my computer. I was starting to think that maybe the game didn't like my graphics card or something until I saw others having similar issues.
I was really looking forward to playing Sims 2. I played Sims 1 on console, some side story Sims game a few years back and I got Sims 3, but I wanted to see how Sims 2 was cause I heard it was pretty good and I was excited about having all the stuff packs and expansions with the base game for free. But now I'm just thinking about uninstalling it....
