Pets Problem! I just got pets for my ibook G4 and It was fine until I went back (after I quit) to a house I made with two pets and it wouldn't open it (the arrow with the flower type lines around it froze there). So I reinstalled everything(saved downloads) and It still would do that! *I have no custom contnet but clothes and hair from thesims2.com *No hacks *my computer does meet the system requirements. *I have uni,nightlife and open for business.
Keep in mind that if a computer only "meets" the guidelines that you may need to turn down various settings, use smaller lots and houses, and the like. So, try turning down your graphics and/or performance settings and see if it will let you get into the house now. The other thing is that sometimes a lot just goes hinky. The best thing to do in that case is to remove the family from the house and then move them to another (perhaps smaller) one. Since you're on "ibook" it is a Mac and for further help you'd need a Mac user. (John likes Macs. Perhaps he could help more.)
