Replay 360 file won't open

I have created a video segment for my course 2x. Each time I have tried to open it I get the following error message.  

"This project cannot be opened. It's not a valid project file or it may have been created in a newer version of Replay." 

Both videos were created in the same version of Replay. I literally closed them and tried to open them again, just to make sure they worked. Has anyone else ran into this problem? This project is due and I don't have time recreate my work yet again.
