Support, I'm trying to register my domain

Hello Support,

I'm trying to register my domain "http://www.flamingseoconsulting.com" for WPMU DEV Video Settings ...keep on getting the next reply: "That domain is already registed by you or another user! Contact support for help."

I used to have these videos installed already when I was using my late
WPMU DEV account: User: [removed], Email: [removed], Pass: [removed]
- The account was cancelled about a year ago.

Please, have the issue corrected. I'd like to have the tutorial videos back on my site soonest possible.

Thank you!
BR,s
Timo
