I'm trying to use Pinnacle Liquid 6.0. Everything seems to be going just boffo except for one small problem. None of my video shows up. Regardless of what format I use, when I try to play or preview or do anything with the video, the audio plays while a giant, ominous exclamation point sits in the screen where the video should be. I'm sure it's something very simple that I just havn't figured out, but that in no way dimishes the fact that it's driving me insane.
