Hello,
I too am having problems Problems.
With Plugins. It seems to do with Ilok stuff... See when I updated Vienna Instruments software, 6 and 7 and added Synchron Player, I get Beach ball on loading all my old TV film projects with 6 Pro and 7!! IT loads sometimes, but other times crashes. It happens on my empty templates too. My templates have 4 instances each having 16 midi. Woodwinds, Brass, Strings, Percussion. It seems to crash when i have all four or more instances loaded. I also noticed the License error in combination. It is like the USB ports on mac is over worked, and ilok looses sync. Then it crashes. When you add Audio tracks with MAS it does it too. I can replicate it too. So you are not crazy at all. Its becoming frustrating now. I love my vienna stuff and built my studio setups around it. Its a resource problem! I think programmers are pushing the limits.
I should make a video too. Also have it with MOTU DP 10.5. Getting rally bad when you can't load a past project for Director without hrs of crashes and cant add multiple audio tracks anymore. Also data corruption in Instruments Pro and ensemble Pro project files. Random values in Pitch. I am sure they will sort it out. Vienna does good when they see the issues.
Kind Regards
B
