Used the program for the first time yesterday and it worked fine.
Used the MasterRig and it’s window opened up OK and I was able to modify the parameters.
After exiting the program and restarting it later, the MasterRig window now doesn’t open.
Clicking the effect changes the text color from black to white but no window.
All other effects that I’ve tried do bring up their windows.
Removed MasterRig from the effect pane and added it back, still no window.
I am running the 64 bit version on an up-to-date Win10 OS.
