I am having an issue where all of my unhitched instruments will not auto load. Marimbas and Vibes etc load fine, but battery, rack combos, drumset etc do not load. I am using VDL 2.5.2, Sibelius 7.5.1, Kontakt 4 and Kontakt Player 5., I also am using the 6.0a template and the Write Score 7.0 Template. It all works n my laptop, but not my desktop. HELP!

I would stick to using only Kontakt 5 in Sibelius 7.x. If you're using any instances of K4, it's probably not going to work as well. As for the auto-loading, that's a function of the template file as well as the sound set that came with your template. Double-check that you've configured this exactly as the documentation outlines. More often than not, it's one little setting you may have missed (i.e. selecting the correct sound set or making sure things are set to ";auto"; in the mixer). If you still run into snags, check with the folks from The Write Score. http://www.thewritescore.com
