For the last two years I've been using Vegas 6, rendering, and burning discs with success. Recently, when I go to render in Vegas or other Sony programs, as an AC-3 file, it won't allow me.

When I go to render as an ac-3, it states that the plugin "wasn't unlocked" but it doesn't give me anywhere to enter the activation code. Huh? Wasn't unlocked?

I'm considering re-installing Vegas 6 but am uneasy about losing project files/loops/etc--even though I have them backed-up.
