Rediff.com India — unable to access mails

Sir, [protected]@rediffmail.com is my mai id but since last couple of days i cant access my mails. While i try to login my id rediff saying that there is an error of wrong password or invalid mail id. But iam very much sure that i have put the right id with right password becaus this is my mostly used email id.. Plese solve this problem. I had so many tymes tried to login my email id but each and every time i was failed to login for which i bear a lot of losses. My mother is a severe copd patient having an old goitr and for her better treatment the doctors team of chennai apollo send me some mails and they also ask her medical reports from me through email but i cant communicate them still now due to not open the rediffmail id an as such i did nt do anything for my mothets treatment
