Rendering Error in Motion File

I am running Motion 4.0.0 and trying to work on a motion file that I have worked on many many times before. However, when I go to open the file these two windows pop up:





And the icon of the file reads this:



The file itself is not corrupt because its saved on a shared raid drive that my coworkers are able to access and open the file with no problems. I've been Googling the issue to see if other people have had the same issue but no luck. Any ideas?

I've restarted the computer; I've tried opening the file from my Finder window as well as from File>Open while in Motion, and no luck.

Thank you!

Thanks! Just tried that but I still have the same problem.
