New to Sony Vegas Platinum, but I have successfully burned a DVD and posted a video on FB. But now I'm having trouble doing the same thing I have done before. Once I have inserted the video and audio I try to send the project to DVD architect and burn. But for some reason it does not show up. Also when I have saved the project in Sony Vegas and wanted to come back, it says the file cannot be found in the specified location. I feel there is something simple that I'm missing here. But it is really making me feel like a complete idiot and is frustrating.

Anyone had these problems before?
