Never seen this before and I've been using MagicYUV for quite some time. Most often without audio but several with, too.

The project loads and all the media play without a problem but every time I open the project I get this message. Every single time. No matter what changes I make.

Ring any bells for anyone? VP 17-452

Since I can't upload images here I'll try to link to the Vegas forum content
