Don't post this under Quick Answers - you need to talk to the admins directly, so ask here:

Only they can examine the DB directly and work out what is going on.
Please give them as much info as possible - the username you tried with, the article you tried on, any error messages (copy'n'paste if you can). You clearly have validated as you posted this OK...
P.S. Give them a little time, they are in Canada, so it'll be awhile before they are in the office.
