Nobody was able on whatever 'communication channel' to reach Jonathan, the developer, the past months.
It left many of us worrying about his well-being at the first place and secondly about the development of Kisslicer.
However, there are several (and recently) reports that people received their pro-key after paying through pay-pal.
That's a sign there is still someone involved, or, that that process is automatized.
