Hi guys I hope you all can help me.
I was working on this project due on Friday and after I cleaned up un used files and did an export i saved and closed. I noticed that I needed to change something the next day and when I went to open I got this error "Error cannot understand project file. I did try renaming the .bak file for both project and history but that did not do anything different. The only thing I did before I closed it it that maybe has something to do with it is that when I was exporting I had walked away for a while and when I came back the project was playing and I stopped it and closed it. The export screen was gone by then.
Any help would be great.
