Hii

As such we can not say whether there can be some option for your or not. But as far as the registration process is concerned, the process is over and registration has closed. And it is very clearly mentioned in the prospectus that incomplete applications would be rejected. 
As of now there is no option to continue the registration. I would suggest that you contact the authorities itself about the same. Maybe they can help you.
Here are the contact details -
Phone - 011 26588500, 26589900 , 26588700

Hope this helps
Thanks!!
