Hey Tim!
I’m able to open the project and individual timelines just fine. There are 3 ‘EDIT’ bins, each with 70+ themes, and some of those themes have subs too. It seems there was a main EDIT folder to start, and over time it was duplicated a couple of times, though I’m not sure what’s different between them.
When possible, I export XML of the entire project at once. With this one, unfortunately, export repeatedly fails due to ‘critical XML error’. I’ve tried thinning things down to get a bulk export, but anything other than a single timeline produces the error. That said, I am able to export individual timeline XML and am in the process of exporting the latest timeline from each theme bin.
Once I’ve got those out, I’ll convert and bring them into a FCPX library and see what’s what.
