I have lot of courses developed using Lectora Tool that need to be modified. all these courses are scorm 1.2 compliant courses. We have only got the final ZIP files with us. We are trying to import them into Lectora Publisher using Import ZIP file option. I chose the File and selected the path for directory as well. When i click on import, i am getting error message " Selected file is not valid zip title". Are we missing something in the process? is there a way we can import zip files into lectora tool and make some edits?
