I've searched through the forums and found nothing like what I'm experiencing. In Create-A-Sim, the sims are too far back to see closely, like a foot away from the mirror, and when you try to rotate them, it flings the screen around to show a tree and a sky.

Pets drop down into the floor, so only their top half is visible, and no one can interact with them.

I've added two pictures, if you don't know what I mean by this.

I have the same problem. Then I logged off, then back on and this will not stop 'popping' up:
"C:/Documents and Settings/Owner/My Documents/EA Games/The Sims 2/ Logs/ Object Error_N004_t403.txt ." Can anyone help!!??

Did you both remove your hacks before you installed Pets? You really need to do this, because incompatible hacks cause these kinds of problems! Only use them if the creator has told they are compatible OR if there are updated versions.
