Welcome to WebmasterWorld Guest from 126.96.36.199
P.S. I tried to transfer the domain names to other registra, but can not.
Which one was it? You may need to check you are sending the request to transfer from the correct email address (those in their records for, billing, technical or admin)
If all else fails phone them up, may take a long time (and cost a lot if you don't live in the US) but in my experience the registrars helpline can usually help if all else fails..
