On www.comergence.com select both the 'Forgot Username' and/or 'Forgot Password' links, enter your email for each and it will send two separate emails to you. The email when requesting must match the one from the profile contact information, other wise the feature will not work.
Be sure to type in your password and username, if copy and pasted it may cause an error. Check your junk/spam folder for the emails as well, as at times they may end up there.
The system email is from firstname.lastname@example.org for all users.
