JohnnyQ: The failure to send the packets could be quite a bit of different errors, about how long have you had F@H installed on your machine? If it's been a relatively short amount of time, could just be a server error on Stanfords part, however if it's been over a week or so, then it's probably a configuration error, or another error. Are you on a dialup? Or a always-on internet connection? Or other highspeed?
As far as the registration date, everyone get's the same date, and all teams have the same date as well. Why it is this way, I really don't know, but it doesn't appear to affect anything. I myself registered on it last summer, when I was looking at it, but it shows me registerting last Sep. Just a glitch in the program.
Edit: Just re-read your post, and well, everything I said is not really revelant.
Don't worry about it, there was a glitch on the servers most likely causing your issue. Has it succesfully sent a WU since then? If not, you may want to re-configure it.
