Why did you mess up Vegas 14. If I render the same project in 13 it is fine.. I am running the new 201 build and had same problem with the older 14...I worked with support and sent them a screen shots of the long list of issues on crash logged into the administrator side of windows 10... I hope you can fix it because I do long meetings for a Government TV station and 14 is now trash to me. Sony 13 is fine on the same project.
