Didn't work for me earlier in the day, but I tried again and voila... the front page loads correctly
However, I am having issues with being logged out and not being able to log back in again... persistent error messages: "Unable to find the requested page." or: The Server at Stardock Net took took long to respond.... "
The only way I'm able to log back in is to close FF and reopen it, then hit the bookmark on my toolbar. Thing is, I'll be logged in for a while and suddenly I'm mysteriously logged out again.
