Hi John. Just to clarify here: you have some courses that have been backed up from a 1.9 course and are in .zip format? You have a version 2.4 and when you go to restore them - for example - you could create an empty course and then in the course admin click "restore" and upload and restore your 1.9 backup - you get the message that the file is not in the right format? With 2.0 you can't restore them so that would be the correct message - but with 2.4 you should be able to restore a 1.9 course and Moodle will convert it for you. So there is either an issue here or a missed step that we need to identify.
