I think it was cyber-gremlins! I tried to copy and paste the link that YouTube provided again with the same results. Then I copied and pasted the url at the top of the browser on the video page–the same exact url as before, mind you–and now it works. Go figure!!!
By the way, the picture is of the gremlin, not the visitor!
Here is the link: How to use the Stamp-a-ma-jig on TheMadStamper Channel. You will find more videos there as well, so take a look around.
Meanwhile, Happy Stamping!
