I just pretend I know what I'm doing with computers. I'm afraid I have no idea why it's not viewable. Let me ask though: Are the other videos on our site viewable to you? I'm asking because I put this last one up exactly like those. If those work, then this last one should work (I'm guessing). The only difference might be the size of the file - which might make it hard to view under certain conditions. Or, I might ask: Do you have Quicktime on your computer? If not, you can download it for free from the Quicktime site. You might want to try that.
