As long as you have sent the first one and sure that you have filled in all the necessary fields correctly, then don't worry.
Sending a 2nd one may just introduce duplicate records into their registration module and make the verification process harder.
Just imagine at this point of time, there's hundreds and possible thousands of records pouring into their system as people rush to make pre-orders. Wait for them to confirm the records, and hopefully send out a confirmation email soon
I know but i just notice that Once i done the Payment on 17/9/2012 1:22:04 am and i fill the registration form and i filled 17/9/2012 1:25AM .... How?
