I've exported the video I'm currently working on twice last week to Windows Media (WMV). But for some reason, today, when I went to export it (using either the Adobe Media Encoder or Matrox Media Encoder) it does nothing when I click OK. It just sits there.
I tried downloading Windows Media Encoder 9 and installing it just in case something had screwed up with it, but that didn't help either. I restarted the computer, still nothing.
