@fatalitygr2: Not sure what you mean. Backing up is just an extra safety step. When you rename the folder you put stuff back after the game created a new one and you work with the renamed one. The folder on the external drive (or anywhere else) can then be used should anything go wrong with the process of putting back stuff.
@melissash:
1. Not able to choose family: You're in tutorial mode now, go to edit town to switch back out of it
2. Just logout and back in
3. Not sure about the picture issue. Is this when you use the ingame option or using print screen ? Mine have been black with print screen in forever. I use a tool for those.
4. Could you make your own thread for the freezing issue. Try to explain what happens in as much details as possible. Could you also post your Computer's DxDiag in that thread.
