Yesterday I had one link open to an error code similar to what P Smith posted. But when I attempted the link again it worked. It seems to be an issue on viglink's servers ... perhaps overloading?
Try the "broken" links again. They likely work, and did soon after their initial fail.
Did try - same sh!t; you can test it here too: http://www.dbstalk.c...058#post2959058
