I just installed a free upgrade to Magix Premium 2019. I now have 184.108.40.206. Now I can no longer import or export mp3 files. I wasn't informed about that major change before the upgrade. I've been using Magix Music Maker since 2013 and have bought three new versions since then, most recently 2019 last May. I have always been able to import and export mp3 files until this free upgrade to 2019 last week. How can I import mp3 files?
