Account conflict between drupal.org and groups.drupal.org

I have changed my username from carlch to cach on drupal.org and I now get a conflict on groups.drupal.org
I would like to be cach on both accounts, can this be fixed? Right now I can not login to my groups account.

When I try to repair account I get the message: "Both an account with matching name and an account with matching email address exist, but they are different accounts. This must be fixed manually."

This is me:

http://groups.drupal.org/user/54488

Thank you!
