Interactive Flat PanelsBlank Screen on Flipchart/ Page Browser shows everything.

This has happened to me several times.  This last time, I put my computer to sleep.  When I woke it back up it had completely shut down.  The program asked if I wanted to recover a flipchart.  I said yes, but then it said the program had an error and had to shut down.  When I opened it again, the file showed about 1/3 of the 20 pages or so, and the rest said they had trouble opening the page so they were replaced with a blank by default.  The ones that show in the browser do not display.  This was several class periods of work and hours of time.  I am not happy!
