Hi guys, need help...

I am using Sony Vegas Pro 8.0c. I tried to render an audio file (WAV) in CCITT format but there was an error message. It says "an error occured while opening a codec".

I went control panel - sounds & audio device - hardware - audio codec - properties...and my CCITT audio codec is working fine.

What should I do now? Is there any free codec that I can download? I tried to find and even installed it but the error still appears. I'm not sure exactly which codec I should find..

Or I do have the codec but Vegas just can't open it?

Help is much appreciated. Thanks in advance.
