PLEASE HELP!!! School project gone... "Unable to locate these files..."
Hello,
I am working on a university school project right now and I have spent about 7 hours editing the project thus far (I am still a beginner at editing, especially with Premiere Pro). That was for the first draft. I haven't been on Premiere Pro for about 2 weeks since then, and now I re-open it and pretty much EVERYTHING is gone?!
I took screenshots to help me explain my situation:
1. Here is where the video and audio files are located, on my desktop in the top left corner.

2. This is what comes up when I open the project.

3. After pressing cancel on that previous picture (I tried searching for the files and it couldn't locate them), you can see that it says that my media is missing...

Does anyone know what is happening? Your help and advice will be greatly appreciated!!!
Sincerely,
A Panicked University Student
