I have the same problem with the presets from the VST Instrument Sets causing Cubase to totally lock-up when clicked on inside of Halion Sonic SE.
The demos have since expired for triebwerk/dark planet/hypnotic dance but the presets remain in HSSE and if I accidentally click on one while browsing sounds it’ll cause Cubase to freeze. It’s very frustrating since I’ll have to force-quit Cubase and lose any unsaved data. How can I just wipe those presets away so they don’t obstruct my workflow?
