new wordpress site isn't uploading

i just now downloaded wordpress through bluehost. everything seemed to install correctly, so i logged on to my wordpress page and started working on my site. when i went to preview a page, it just loaded up my old content (my portfolio site that i was working on but never finished) and not the new wordpress theme. not really sure what to do. i downloaded cyberduck and it shows all the wordpress files has been uploaded. i don’t want to manually install and rename files and things like that. thats why i did everything through bluehost. thanks a lot for your help!
