Trying to install – Can't get rid of "parked" page

I just signed up with Bluehost and I have installed WordPress. When I go to activate a theme, nothing shows up on my domain name. I’ve double checked that all the info is correct and tried reinstalling. Nothing seems to work. I do remember that the first time I installed it said it was overwriting some files. How can I fix this problem? I’m new to all this, so please be specific. Thanks.
