Registration problem

Hello there,
I tried to register with wordpress.com yesterday, but all I got was a blank page after I clicked on “register” button.
Today, i tried to register again, but it says the username (which i used to register yesterday) is allready taken. I tried to use “forgot my password” but it says that the username does not exist!
I did not recieve any confirmation e-mail or activation e-mail. Can you please send the activation to me so i can continue to register with the same username? The username which I used is: mobilguru.
the e-mail address which I used to register is:
***removed***
