Exporting Audio Problem

[SlatersGarage]

Hi all...

Here's one I'm sure has been answered a hundred times, but I'm still pretty new at this, so I hope y'all will indulge me...

I'm trying to export an animation to .avi, but the .wav file I'm using as the soundtrack doesn't seem to want to export with the final video file...

It used to work with earlier animations, but now something's amiss, and I can't figure out where along the chain I've gone astray...

The corresponding DAT file is good, the corresponding Papagayo file is good, and the raw .wav file is good... It plays in the timeline, as well as on its own in Windows Media Player... It just doesn't seem to be there when I export the .anme file...

Any suggestions?

Thanks,
Slater
