When I first installed V11 and NB Titler everything seemed fine. Then oddly, NBT crashed Vegas every time I tried to put an event on the timeline. Then NBT put out that update and it started working again. Today I installed Build 425 (Vegas 64) and now NBT is broke again.
I've found NB Titler to be very flakey with x64 and fairly stable in x32.
After I upgraded to the latest builds of Vegas x64 and NB Titler I'm getting messages my nVidia card isn't up to snuff for work with NB Titler when I had been receiving no prior error messages about incompatibility. I seem to be going backward.
