Where is your steem now? You have a steem account (which is obvious by you posting with it), you should just be able to transfer it to the account by it's name and it's loaded onto the account.

Vessel itself just loads private keys for accounts - there aren't multiple addresses like other crypto currencies. Your name is your account.

I don't know much about the CC process you're talking about, so I can't speak to that.

Hope that helps hah :)
