Used the fix above but have had no success.
Problem does not appear to be with the binder code, as trying the above fix resulted in the binder looking right folder wise, but without content. When I copied the content folders across, I again got a message that the project is incompatible with the current version of Scrivener.
I’m using Vista on a Dell Inspiron. My computer did shut down last night while Scrivener was still open. The tutorial file still opens perfectly well.
