Re: Pro 9: Rendering failures using MainConcept AVC/mp4?

Hopefully there's a fairly simple answer for this that won't call for waiting for the first patch to Pro 9.0.

From the time I installed Pro 9.0 a few weeks ago, I have been unable to render using the MainConcept AVC/AAC codec combo. Sony AVC has worked fine, but in Pro 8.0c I'd become accustomed to using MainConcept over the Sony version and would at least like to compare them. Since search did not reveal this as a screaming issue either here or on Sony's own forums, I'm guessing that perhaps the codecs simply did not install properly or I'm missing something else in the set up.

When I have tried rendering using any of the existing presets that came as part of the basic installation, a fatal exception occurs that crashes Vegas Pro 9 completely.

Following are the "problem details" that are provided in the problem report module that pops up after Vegas freezes:
