Just a thought. I had a friend who had to redo his computer from the beginning. When he put NTL back on it gave the same message. He was convinced he was putting the right password in. He rang the NTL helpdesk and, after answering some security questions they told him his password. NTL passwords must have a number on the end. He had the right password but had forgotten it needed a number as well. For example he knew his password was, lets say, apples but with NTL he had forgot it has a 1 on the end (or whatever number you like). Problem sorted. Ring the helpdesk on 0800 052 2000 and, unusually for an ISP they will tell you your ID and password over the phone.
