Failed to load project

I've got an hour-long documentary. All the grading is done.

Now, of course, I get 'Failed to load project.' There's nothing in the manual that covers this situation, or where or whether Resolve stores older versions of a project that you can recover. I apologize for being a noob.

I was able to export the .drp from the project screen, but it's only 17K, and reimporting it to another project results in nothing.

Can anyone from BM help me out here?

find the tech support page and email to them, if you have a paid license (of course) they might be willing to help you faster than if you have a lite version. Is something that (i think) only BM can fix for you.
