save/reopen error

I finished working on a project after 4 hours. I clicked save as and typed in a name for it and saved it to my desktop. Now I can’t reopen it as it says “Couldn’t find the project data folder: ‘the name i entered’” I really need this project to open up again please help ASAP

Projects are two things: the AUP file which is the Project Manager, and the _DATA folder which actually has all the show stuff in pieces. Can you find both?

What did you call the show? Did you put any evil characters in the name like punctuation marks or foreign characters? I generally avoid surprises by only using numbers and letters and no spaces.
