your e-mail have been confirmed.
Though the fact you didn't get that e-mail would be a concern, as you'd probably not be able to receive other e-mails regarding your account either.
Anyways, it appears as you do not have a pending hosting account anymore, due to the time before sign up and confirmation of e-mail no doubt. Login to the account panel using your forum user name (or e-mail) and your forum password, and start sign-up from in there. This for two reasons: 1. the e-mail would be locked to this account, 2. you need forum and hosting accounts to be linked in order to keep the account active.
