What kind of product grants a ten-minute demo period? That's most likely a bug that got introduced with a recent update of the plugin. Which one is it?
It's the VKFX Preamp, but I don't recall ever updating it. When the dialog box appears, the settings on all the instances of this plugin revert to default. Although the message says 10 minutes, it doesn't happen every 10 minutes. More like 30 minutes. And this only ever occurs in one project, i.e. the one with VKFX Preamp in an fx chain.
I never use the TH3.
