"files not found" error - sounds keep dumping into trash
I'm using garageband 10.3
I've been recording lots music lately, but sometimes when I open up my projects, I get an error saying that a huge list of the tracks I recorded were not found. After investigating, they keep randomly dumping into the trash bin. But I can't seem to restore the tracks into my project.
so I have two questions:
1. How do I prevent this from happening anymore because it's super frustrating, especially after I invest multiple hours into a song, just to have to retrack all the missing segments.
2. How do I restore the files into the project?
Thanks!
