Special thanks to @Yamaha_gurl for helping identify an issue with our support system. I believe this to be a firewall issue with our host. I have sent off a request for them to look into it. I have a temporary solution in place, but have no idea how long the failures were taking place.
If you submitted a support request (question, avatar, registration) and did not receive a reply, please submit your request again, my apologies for the inconvenience.
