I show the account is active and you should be able to sign into it just fine to submit a Support Ticket on the downed site.
Go here https://panel.dreamhost.com/index.cgi?tree=support.msg& to submit the ticket.
Unfortunately there isn’t much I can do directly here over the forums. This is something that one of Support Techs would need to address for you.
If you are still having issues let us know!
So I looked into your account and I was about to find that your domain wasn’t registered with us.
It’s registered over at http://www.tucowsdomains.com/
You would need to contact them about getting it renewed.
Your domain is hosted with us however!
Hope this helped!
