Problem adding add-on domain

i keep getting

“This domain has already been added!”

when trying to add an addon domain, i think its since i added a domain on an account i deleted since the name was too long and i could not create more than one mysql database, hope this can be fixed, my old account name was stuntingforever

i also made a support ticket, the id is 291142
