I think it's been 48 hours since I registered for the Second Shot offer and the voucher number still hasn't arrived. I just registered again, and likewise I did not receive a voucher number or confirmation email. Both times though I was directed to this page: http://img149.imageshack.us/img149/4785/nosecondshotpo4.png
Thank you, it's just as you said. I still don't know why I was seeing that screen I posted before. I didn't see it this time...anyway got my voucher, testing tomorrow! First time taking a Microsoft Exam (ahhhhh!), so this is great to have.
I have another question if you guys wouldn't mind: If I pass my exam the first time, am I eligible for Second Shot on another exam? I guess that's asking a lot, but MS never fails to surprise with its generosity.
