my project file could not be saved
on 2nd June I installed Storyline 2 on my computer. When I wanted to save my project file, I got an error message: The project file could not be saved. Method not found: 'Articulate.Document.IpackageProperties Articulate.Document.XPackage.get_PackageProperties0'
I checked the Q&As how to solve it (delete your temporary files), but I am still not able to save my project file. Are there any other solutions?
