Thank you very much for your feedback! Also found some useful info in the link below. I presume the MindJet Publish feature (recommended above) is not available for reader accounts?

Aha, now I see. You are using the obsolete and retired version of Mindjet files in your browser. You must have a recent Mindmanager version installed on your desktop for Publish. Why not download the free 30 day trial to save your maps. And you may want to contact support.
