I've been using Movie Studio since Vegas Video 3.0. Along the way I have upgraded from Movie Studio 10 to 13, 14, 15, and 16. I recently had to reinstall everything. I upgraded to Movie Studio 17 Platinum, at the same time. l. When I attempt to edit a previously created .vf file, I get a message that the following plug-in is not on the system. SVfx:com.NewBlue.MSPPSAutoContrast. I have discs for Movie Studio 10, 13, 14, 15, 16. I have tried re-installing them (and the plug-ins on them). Still not found. I have verified that I have NewBlue Elements, Essentials, Stylizers, TitlerPro2 and Transitions are installed. Where can I find NewBlue AutoContrast? I use it a lot. Thanks.
