Thanks for the post Edward.
It may not be entirely New Blue problem. The Vegas Pro 11 build is extremely buggy and unstable. There are multiple threads on the Sony forum with stability issue.
I have (for the 4th time), done a factory reset, updated all drivers including TI Catalyst 10.11 and did a fresh install without any Antivirus or other software on machine. This time, I did not install the New Blue Fx Titler at all. The Vegas Pro 11 still keeps crashing whenever I use any GPU plug-in. Once it crashes, it stops rendering as .mp4.
I have provided all the detaisl to the tech support team on the New Blue Fx team. New Blue Fx team, by the way has been very prompt with responses and acknowledging issues (with ATI driver) even on weekends. The Sony Guys have not responded since Thursday and not available even who have purchased their paid support services.
For now, I’m reverting back to Vegas HD Platinum 11 license I have till there is a new build of Vegas Pro 11.
Thanks.
