6.10 changed quite a few things on my end… now even your imported plants don’t seem to appear in my test instrument, and a number of my instruments throw init errors and such.
I think I need to play with this a little more before sending anything. Hopefully I can get it straightened out a bit. I think working with previous c2lite versions over the new cs6.10 might help me unravel some of this, but right now I need a break 
edit: but FYI I am still seeing a significant difference between c2l and c2h with regards to my instruments using the newest installer and it’s included csound package.
