I had the same issue: not being able to logon to OKC for a week from two different home computers (with two different browsers and even after eliminating cookies and history) and from the app on my iPhone, the same "Sorry, we're having technical difficulties right now. Check back later." message, the same lack of response to my emails to OKC, and this while still getting emails from the OKC staff robot and trying to log in directly from the imbedded link... BUT EVERYTHING CLEARED UP when I shut down my home modem and wifi for five minutes and started them again.
