I'm trying to load my library into Kontakt 5 (new install of VDL 2.5.5) and I keep getting the error message that the library won't load.  I have tried the workaround listed on this site (Activating from the service center first then going back in to load the library) but even that isn't working.  The library box will show up in Kontakt and I can click on the keyboard to make sounds but it won't work with my controller and I can't access the library in Playback Devices in Sibelius.  Anyone have any advice?
