Does not work on snow lepord

All I get on launch now is a black screen. I have uninstalled and deleted all the plist files. Still can not get past the blank screen. This app is unusable. When it did launch for me, I wondering how Apple approved it. It was completely unintuative to use. My daughter (10) whom I purchased this for was unable to get it started and load her profile even after I got it started for her. I had a hard time finding out how to load the profile and finally found that I just had to click in the right blank spot. This is the worst edu geared app I have ever used....
