Hi @mayurakshi,
That sounds really strange, I just tried it myself without a question and was able to register successfully.
What web browser are you using? Make sure all the fields marked with a * are filled out, such as first/last name, email address, postcode etc.

Could you try again for me please?
Thanks!
