Load Project Error

Hi I have been using Animotica for 12 months now and love the easy interface. 

I can not open any of my projects at the moment and get a load project error. 

I have tried to open the matching auto-save file from the folder and I get the same error. The project files are stored on my one-drive mirror folder, and I have ran chkdsk already?

Any other way to recover these damaged files, I have 87 projects!!
