Initially I got the screen you did... then nadda
So I went back highlighted my name and hit Enter.
Magically a 'my role' or something appeared... I entered it... nadda again
Sooooo I went back to my Name, highlighted it again, hit enter and kept doing this going down the list.
Finally Boom! no submit button... just a big.
I am entered... If I win I will pass it on to you
Hi Jayanta, this is a web page certificate error that comes up from time to time. We will look into the cause and report back. In the meantime, you might try using Chrome (it works for me).
