I'm trying to make a movie and put it on a DVD.

A few steps into the process I get a message telling me that the DVD architect is not installed. I downloaded the Vegas movie studio from Sony's site; I have no CD to reinstall the program, and I'm wondering what to do.

Do you think there could've been a problem downloading the program? If so how can I fix this? Is there a place I can go to re-download the program?

Or should completely different path be taken?
