Winclone Restore to Boot Camp fails because of "invalid image" error

I bought Winclone so I could expand the size of my Boot Camp partition. Followed the directions to make a Winclone image of Boot Camp, went to Boot Camp Assistant to make the new partition (as the directions told me to do), got the machine distributed as I wanted it to, and went back to Restore from the Winclone image. Read the website, watched the youtube video… but the “Restore” command leads me to “Invalid Image: the image you are attempting to restore does not contain the correct information.” Help???

This is usually a sign that there was an issue with the image. How long did it take to create the image? What is the size of the image?
