Hi @Chayan
There is a check box missing from your view when you are registering, I have provided a sample screenshot below with the location of where the box should be circled in red. Make sure that you are not using a mobile device and try to use another web browser to see if you are able to view and check-mark the box in order to register.

Once you have checked the box you should be able to click on Register to proceed.
