Indian Railway Catering & Tourism Corporation [IRCTC] — otp verification

Hi sir, i created user i'd and password at irctc website and i had received the otp for user i'd verification but i didn't done the verification and after 15 days i tried to verify my user i'd by using same otp (15 days back otp) but when i put otp for verification it will show processing and it won't finish it up and i waited for sometimes one hour also but could not. I tried many times but till now i am not able to verify my user i'd.... I have to book ticket for travel purpose. Can u help me to get it done?...
