Can't Login To WPMU DEV

Hi,
I must have done something wrong with the installation and I am getting the following message when I try to login to WPMU DEV from within Wordpress.

This domain has previously been registered with WPMU DEV by the user RoyMorejon(i**o@commandpartners.com). To use the dashboard plugin on this domain, you can either login with the original account (and upgrade it if necessary), or upgrade your trial to a full WPMU DEV membership.

Thanks,
David
