Jntuk — Unable to login/ reset password

Hi Sir/Madam,

I am Khageswara Rao. I forgot my password and when I was logging it was showing invalid credentials and I can't even change my password it was showing mail ID is invalid.
forgot password option seems to display invalid email id, unable to retrieve the password by using forgot password.
trying to register with another email id not working.

Please do the needful ASAP.
