Registration key for Mapsettoolkit

I have used Mapsettoolkit for a number of years (version 1.77), but when I attempted to use it a few weeks ago I received a message that my temporary key had expired and I should enter a new one. I then clicked on the buy a key button and was taken to the GPSMAPPER website, but could not find where to buy the key. I then emailed gpsmapper requesting to buy a key, but have not received a reply. Any help will be appreciated.

I now realise that it is cGPSmapper which is asking for the key and not mapset.
