Flash timeline blank, as well as canvas... (corrupted?)

DISCLAIMER -- I am using an old version of flash, so things work differently. I am animating with Macromedia Flash MX 2004 7.0

I've been working with flash for about 6 months, this is nothing basic I've messed up, I know how to start a file, I know the basics.

When I opened up my flash file that I've spent about 2 weeks on the timeline was completely blank, as well as the canvas.

This is especially weird, because I can open another file easily,

And I can even go into the symbols in my project.

It's a very weird issue, that I can't fix.

I was worried that the file was corrupted, so I tried accessing an older version, since I had the file in one-drive, but none of the about 20 versions will open, it's always blank. I've tried restarting both flash, and my computer several times, and I realize it may just be a problem with the oldness of the software, but it's weird, because opening other things still works fine.

I had about 40 hours of work on that file, and was hoping someone could help me out.

Thanks!
