I'm sorry you're having problems with H3000 Factory, but there is no conspiracy afoot.
There is a recently discovered problem with some of our plug-ins on some installs of Cubase 7.5 and Cubase 8 on Windows. As far as I can tell, this doesn't happen on all installations of Cubase on Windows, but it does happen to all plug-ins built on the popular JUCE platform, including ours, and it has been determined that the problem is in Cubase, not JUCE. Steinberg is aware of the problem and has promised that the next releases of Cubase 8 and 7.5 (as well as the next release of Nuendo) should fix it. This information is publicly available, though perhaps difficult to find.
It does appear that this maintenance release for Cubase is scheduled to ship in March.
I realize that this doesn't solve your problem, and I'm sorry for that. I believe you have been in touch with Jerome, but if not, please contact email@example.com and we will try to help you any way we can.
If you're curious, here is a forum post detailing the bug itself.
