I am having a terrible time getting Kontakt 5 to load my VDL library. All of the files look to be located in the right spot (nkx files under Virtual Drumline 2.5, sounds xml template placed under Sib 7 Sounds, etc...), but no dice..... I called Avid to see if this was a Sibelius 8 issue, and they  were a huge help (insert sarcasm...).  I can't even get the VDL sounds to load in a standalone version of Kontakt, even though they look to be placed in the right file.  I continue to get a load error message from Kontakt. 

I am not sure what to do next.  I can't get any playback at all with VDL! 

I am running the latest version of Yosemite, Kontakt Player 5, Sibelius 8, and VDL 2.5.  Please Help!

Sorry to hear you are having problems! I would say it is probably time to fill out a support ticket. Visit https://www.tapspace.com/hesksupport/ and fill out a ticket. I will be there to help.

Thanks!
