Many thanks for the reply - will contact support and see where it goes. Regarding setting up company - I am aware - but thanks for a reminder. In my case this won't work. I am not looking to make money, the app is cross-platform freeware. Also I am not based in the US and setting up a company would have serious tax consequences for me. It would also mean significant costs (setup, accounting, reporting etc) which really don't make sense for me to bear just for the label on a certificate! Thanks again, much appreciate the help!
