Hi akewl, welcome to DH!
The full paid confirmation email does not mean that your account has been approved. It takes some time to activate your account. Once your account is approved, DH will send you an email with the passwords of your ftp user and first email user.
I think you stil need to wait for a while.
Don't forget, you can always log in to DH panel and contact DH support in DH panel --> Support --> Contact support.
