Me too. Very helpful message that is.
Yep still getting this error message. Cannot find any information. FYI this is when syncing using ADE app on android phone. HALP I am teaching university students how to use ADE next week would be good to get an answer! Also would be good for ADE to have 'premium' support available for free to libraries. Thanks.
Same problem here. What does it mean and how do I solve this???
