Vegas 7, error opening Lame MP3 codec

I posted this question previously in the Vegas Video forum, but now I see that it might be better off here.... apologies.

Anyway... I am trying to render video using the XVID codec and, of course, MP3 for audio.

On this new installation of Vegas 7.0e, I have a "lame mp3" audio codec offered. Strangely, I do not have that on my older installation (same machine, different OS installation).

When I specify the Lame MP3 codec, I get "error opening codec" when I try to start rendering.

In the past, before Vegas offered Lame Mp3, I have successfully installed and used an alternate MP3 plug-in codec. After experiencing the above problem on this build I tried installng this alternate codec. This codec does show up in the selection list as "MPEG Layer-3" (as it did on my install that had no "Lame MP3" offered).

However the selection of this alternate codec does not "stick". If I try to save these settings in a template, Vegas reverts to the Lame MP3 codec. If I merely switch over to the video or project tab, then back to audio, Vegas again switches back to Lame MP3. Same if I click "ok" from the custom template dialog, then open it again -- it's back to "lame mp3". Which of course doesn't work ("error opening codec").

Is there a secret to getting the Lame mp3 codec to work?

Or, is there a way to get Vegas to forget it exists, so I can use the codec that works?

Vegas 8 doesn't do any better. Exact same symptoms.

I know this "Lame MP3" codec comes with Vegas -- why can't Vegas open its own codec??!?

Incidently, Sound Forge seems to use the exact same Lame MP3 codec, and has no problems opening it!

This btw is under Windows Vista x64. However I've seen the exact same behavior under XP on x86 (Vegas 7), so it's not an OS issue.

It may be a codec configuration issue, but if it is, I have no idea how to fix it.

I have one XP system on which I've installed Vegas 7 where it has no "Lame MP3" codec, just the alternate one I installed. This works fine. But that's an old, slower machine. I hate to keep running my XVID rendering jobs on that machine. I shouldn't have to do that.
