re installing

Hi i don't know if this is the right place to be posting this but here i go.  Had to do a system wipe so i didn't back anything up.  I bought sins of a solar empire though steam.  Its asking for my to do a stardock account registration which i don't remember doing. but, i said ok i will put in user and pass no luck.  It says its link to an account.  but i only have one email so has to be it.  I did the email support no answer does anyone know what i would need to do or a phone number i can call stardock?
