HELP! My posts and orther content is gone after upgrading

OK I am a total noob and most of this stuff goes way over my head.
I tried to upgrade WP myself by following the detailed instructions.

Now my site shows up with no content. No posts or theme settings are working. However all my plugins and themes I DLed are available in the WP dashboard. My site looks as if it is brand new… look… http://www.nauticaljournal.com

I use bluehost.
I backed up my site before upgrading.
Can I import my posts, photos, and settings?

please email me at unsetdeuxs@gmail.com

thanks
