Nice site and you can still see it via
http://hawkeanddove.com/index.php
Your login page is http://hawkeanddove.com/wp-login.php see if that still works.
Edit: Scratch that, you are not seeing the dashboard correctly. Skip to the hacked part of my responce.
You've a lot of reading ahead of you. Start with seeing if you can get your install working.
Backup the all of your files (if you had a good backup you would be able to rename your WordPress directory and just restore the whole works...)

Change your passwords, someone put a file or files on your installation. That could have happened via a password compromise or WordPress/plugin hack since you're site is not maintained and out of date.
Once you have your files and database backed up and safe, look in your directory for index.html. Delete any index.html files and you should be good for now.
If it comes back then read all of this:

This is a good explanation of cleaning your database.

Once you're good, read up on upgrading your version of WordPress. You are running version 2.1 and that's not a safe thing to do. You'll leave yourself vulnerable to more hacking.

Good luck.
