Thank you for your post! We are aware of this issue and we can provide you with a fix. This error occurs when you have not yet created a new document in Illustrator. In order to fix this, please reopen Illustrator and click “Create New” to create a new document before opening the MAPublisher Importer. Once you create a new document first, that preference will be written and the error will not happen again even if you open Illustrator and click Import before creating a new document.
Please let me know if that works for you! If you have any questions, please don’t hesitate to let me know, or send an email via our Support Centre form at help.avenza.com > Contact Us.
All the best,
Avenza Systems Inc.
