MP3 encoding

When I was exporting my Cubase files to mp3, I would get a pop-up saying that I only had so many encodings left. Then it had the option to continue or to go to the online shop. I pressed the online shop and it directed me too an elicenser. When I ran out of encoding I could still convert my files to mp3.
I am wondering has anyone seen this pop up p before.

Yes I got that pop up yesterday but the decoder still worked. I ended you buying a license from Steinberg as it so cheap. I will be doing a lot of exporting to MP3 so it is worth having it.
