National Institute Of Open Schooling — nios. d. el. ed teacher registration

Address:	492001
Website:	www.nios.ac.in

I am arundhati ganguli, teacher of bss pranavananda academy, cg. I have tried to register my name in nios.ac.in for teacher's registration 2017 in d. El. Ed but at the first attempt while doing the payment the server got down and my payment was not done. So, when i started doing my registration again i was barred to do that with the same name, same father's name and mother's name. So i have changed my surname from ganguli to banerjee as i had the surname banerjee before marriage. But this time after submitting the form the ' dbo. Teacher ' error is showing.
So, i am requesting to help me out from the above mentioned situation.
