Weird alert when exporting mp3: "No more encodings. Alert text"

This happens whenever I want to export a .mp3 of my flows.
After I click OK, encoding happens normally
Is this normal?

Thank you pianoleo, will follow those steps.

When export finishes successfully there is no need to worry, you can ignore the warning.
We don’t know exactly where it comes from, but there was a time when MP3 encoding needed a special license, because of the patent ownership from Fraunhofer Institut.
The patent recently ran out and now anybody can use it for free.
If it is not too big a nuisance for you, simply ignore the warning.
If it bothers you, then you somehow need to clean up old licenses in the eLicenser Control Center.
Try running the maintenance task and see if that already helps.

OK, no annoyance at all, it’s just strange. I’ll run the maintenance to see if that changes, but it’s not a big deal at all.
