I'm working on DVD Studio Pro 4 but it won't open the projects I created on version3 on a different computer, it asks me if I would like to update this project file, I say yes, it starts to load project and then comes up 'this project could not be opened. Any ideas?
It could be that DSP 4 is not finding assets. I'd put all original assets and project file on an external drive, open it in DSP 3, relink, save as. And try opening that new saved-as project in DSP 4 from the same drive.
