Wordpress Upgrade Error

I received two separate messages about the auto-install of my Wordpress upgrade. One that it was successful:

[i]We just upgraded your install of wordpress as requested at:

Important! Please visit http://www.stmatthewgr.com/wp-admin/upgrade.php
to update your database tables! Otherwise, you may see database errors or missing entries.[/i]

And directly after that one, that it was unsuccessful:

[i]We were unable to set up wordpress as requested at:

The problem was directory /home/nkeeth/stmatthewgr.com/wordpress doesn’t exist! Unable to upgrade!

Please correct this and go to our web panel and re-submit your
wordpress upgrade request.[/i]

I can no longer access my site at www.stmatthew.dreamhosters.com and I don’t know how to fix it. Please help!
