As always, many thanks for your kind feedback and I entirely share people's frustration with FastSpring but I'm afraid there is very little I can do about it, and as others have said, it seems its the way everything is going to become in due course for commercial on-line downloads across the world.
I just wanted to take this opportunity to highlight a key feature that some customers have overlooked...
Chromatix features a 4-voice/partial layering engine calling up a bank of 56 multi-sampled instruments.

If you click on the LCD display above each channel you will gain access to a pull down menu allowing you to select the voice/partial of your choice. There are two different banks of sounds assigned to channels 1 & 3 and 2 & 4. This is designed to encourage layering of different elements without having to sift through a menu that barely fits on the screen.

The number of permutations across all four channels is pretty mind boggling but if you throw in the fact that each channel has its own ADSR, continuously variable EQ curve control "Tone", LFO, Panning and velocity sensitivity controls the scope for some pretty complex velocity-sensitive evolving layers is significant.
It is also worth pointing out that any sound patch you dial up in the layering engine can be saved for loading later by simply saving the instrument (.nki file).
Similarly you can select which room emulation you wish to use in the effects section by clicking on the LCD display at the top. Just be aware that some of huge reverbs available may cause glitches/pops on machines with marginal CPU bandwidth.
