I am sorry you have not heard back. There are others who have, so I am unsure what the difference is. I don’t use the two modules in HALion 5 that you inquired about to let you know they are, so again I am useless to help you further. I have not read anything bad about them, but if you are directly comparing them to another plugin, you clearly have requirements that need to be met to be a worthwhile investment. Have you tried contacting Matthias personally via a PM to see what can be done?
In this regard, I can clearly see how this would be frustrating and if this offer was available on a store level, you would have already bought it without this hassle. I know Steinberg will gladly take your money and they are offering a solid product, so I hope something can get worked out for both of your sakes.
Best of luck.
