Admin username and password not working after upgrade

I had the problem with the malicious code being inserted into .htaccess files and google flagging the site as bad so I cleaned up .htaccess files and currently installing the 1.4.1.6 update. Not sure what the previous version was but I only installed it about 3 months ago so it's not that old.
I read in your instructions that I needed to double check my admin login as it cannot be recovered during the update process so I made sure I did that. Then I uploaded the new files to the server and went to setup.php page which is showing Zenphoto Setup Upgrade heading and asking me to login. My admin username and password are not working though! I tried entering the captcha and resetting but that doesn't work either.
What would you suggest? This is the site: phase5photography.com/zenphoto
