trying to use pianoteq in two apps on same computer

I own a fully registered copy of Pianoteq 6 Stage. I have been using it in my VST Host (Cantabile) with no problem. I've installed a DAW (Mixcraft) and called up Pianoteq into a track on Mixcraft. When I pull up the Pianoteq interface, it tells me that I'm using a trial version. I don't understand why this is happening because Cantabile is registered on this computer. So shouldn't I be able to the registered version on more than one software application?

Found the problem. Mixcraft was looking in the wrong plugin folder. Once I pointed it to the correct folder, it loaded the registered version
