Error when I register in Free DNS Manager

[bording]

Ooops!   
A general error has occurred. Reason: Perhaps you are trying to view a page that you are not allowed to view, or that one of the filters has detected an injection attack. If you are seeing this message, there's a good chance we haven't written a decent error message yet.

How to get this done?
I receive this error when I click save.

Pls help.
