Sibelius 8 was working (relatively) fine for me for months. After several crashes, and reboots, and little help from Avid...I decided to uninstall Sibelius, then reinstall. As you may or may not know, this means I now have the most up-to-date version of Sibelius. This has proved to not work well with my VDL, or Kontakt 5, or iOS 10.9.5. One bug will get fixed by me doing the little I know with template, sound configuration stuff, then some other problem will pop up. Right now, it is Timpani part being read as Glissando or FX. I tried opening Kontakt 5 and running VDL on stand-alone mode, and it said "error writing files to disk, library will not load." I have no idea where to start.
