Hello, 

I need assistance with a HD Movie Maker PRO project.  I have been working on it over several weeks and always save the project.  My computer updated this morning and afterwards I worked for 2 hours on the project.  Now this afternoon when I open the project, there are not photos or videos - the whole timeline is blank.  If I add a random photo, the previously designed soundtrack comes up with it - the data must be here somewhere - it's an important project due tomorrow - if anyone can assist, I would be grateful as I am not able to start over. App version 2.9.17.  Windows 10. 

Thank you!
