Well, for the first time ever, Melodyne crashed my Sonar Platinum yesterday also. After the crash I couldn't create another region fx until I closed down the pc and re-booted. Then all was fine again.
I'm not running Win 10, i'm still on 8.1 so I in my case it's not that. What I did when it crashed was delete a clip that I had created region fx on, but not rendered. Straight after that I went to create another region fx on another clip in the same track and Kapow, down she went! I'll try and reproduce it and report if I can. The fault logger worked but the studio pc isnt on the web, so it didnt send.
