After downloading the above lates version to solve the problem with the license activation, I fell into another problem. I have set the synchronization time 1. on startup and 2. every 15 minutes (see attached image). EMC does not respect the limit of 15 minutes and therefore but if I click the refresh button on the 16th minute new enails are downloaded. It’s a bug to be solved!!!.
OS Win 10 Pro.
