how to "transfer" objectweb membership to ow2 membership

[tran.huynh@xxxxxxxxxxxxxxxxxx]

Dear OW2 administrator,

I own an ObjectWeb account (account login: huynh) and from the 
the instructions at this page: http://joining.ow2.org/registration.html
it says that I just need to edit my profile in order to become an OW2
member.
The problem is that when I click on the link 'edit your profile'
the systems asks me to login. I enter 'huynh' as my login and then I
enter my password. The system will then refuse to let me log in as
it says : "Error: 'huynh' is not a registered username."

What can I do to edit my profile?

Best regards,
Tran Huynh
