I've been having this issue for weeks, and have not been able to find a solution. Whenever the Captcha pops up (every 30 minutes or so), I instead see the attached error (client error 117B). Has anyone else experienced this? If so, how did you fix it? This happens on two computers, in FireFox, Chrome, and Internet Explorer… it's almost as if it is related to my IP address, router, or something like that. So odd.
