Hi,

We are using the asp.NET membership controls with the Umbraco Membership system. We aren't tracking anything other than the standard fields that umbraco uses.  The code appears to work correctly, but keeps claiming that any user name (even ones made by randomly mashing the keyboard) already exist in the system.  When I check the umbraco Members section in the backend the user most certainly is not present in the list and does not appear to have ever been created.

The exception I get is as follows: (note that I've changed the username from the exception to xxxxx - the exception happens no matter what xxxxx happens to be).

Any ideas on what would cause this?
