I believe the patents on mp3 have expired. So aren't the warnings in the help files about mp3 license expense obsolete?
Can you please tell us more exactly where you find this warning?
Well there's one in the "Exporting your project" section. There's also one in the "Importing audio/MIDI files" section.
I could only find a warning in the 'Exporting your project' section. I removed it now, thanks.
