Hmm. You're not giving us much information to go on, but we'll use our powers of telepathy and read your mind to figure out what steps you've taken to date and determine what you did wrong.
Either that or we'll just take guesses and hope for the best.
Is this a new site? Are you sure that DNS has propagated? Did you register at DreamHost or did you register at a different registrar? If so you'll need to change the nameservers at your registrar.
If you give us your domain name we can check if your site looks fine here. If it does it might be that you just need to clear your browser cache.
I really don't want to waste too much of your time shooting in the dark. Give us more details about your situation and we'll be able to be more discriminating with our advice!
