I have never had this problem before but it has happened today all day.
I open up my sims about 5 minuets from playing the computer mouse turns back to a white one, ( Its blue when playing the sims ) Then I cant do anything like close the window and I have to turn it off and on again. then after a very Looooooog time I get a message saying the sims 3 has stopped working. At first i thought it was the new patch, so I uninstalled my sims then reinstalled them. (Lost all of my files.) It still happens even if the new patch isn't installed. Has this happened to anyone else, who might knoww how to fix this?
