Dance Formation

I thought this app would be a great tool for my choreography but after entering data for several hours work I closed the program. When I reopened it the entire note section was missing. Understand, it wasn’t just the notes but rather the entire note entry feature was gone. I also no longer have options to change colors for each dancer or to use any function except drawing. In short, I think I wasted hours of time and lost my choreography. There would be used for this app if it was functioning correctly.
