Ah yes, should have mentioned that I tried all manner of that strategy as well.
Have tried importing the Entire Project into a New Project and it says “The importer reported a generic error.”
When I try to import just a sequence, it brings up the dialogue where it will display the sequences, but when loading the sequences it just hangs at halfway.
I’ve also tried bringing it in via the Media Browser, and same thing, the status bar just hangs mid way.
