None of my aup files will open

First…I’m not very tech-savvy so please answer as if I am an idiot.

I cannot open any aup files…only ones that have been saved as an mp3 already. I get an error opening project message every time…
Couldn’t find the project data folder
Could not load file

Please help! This is show that is supposed to air tonight.
