I just purchased virtual families on my Itouch straight from the store and everything was working fineand I love it. But it began to crash upon starting the application but I would just restart my itouch and it would work fine but I've had to do this multiple times. Today (7/17/09) I started the application and it was doing fine but soon crashed, I restarted it but when I opened the app again it hadn't saved and I lost everything. When I started another family I had closed the app so that it could run on it's own for a while but when I opened it again it had erased everything again and it's continued to do that everytime I close and open it again even after restarting my itouch. Other topics have given me the answer to this and I've yet to try but will soon. But other than that it's been fine for the most part. 
One other problem I've had is the store not restocking entirely. I went back to the store and it hadn't restocked everything except for the encyclopedia which was the same one, and the clothes which were always different but everything else was bare. I saw that you hit the 'R' key but that's for the computer version. How can you fix this on the itouch version of the game?
