Installation Directory Changed…

I originally installed my wordpress to a subdirectory /prelaunch/. I then moved all the files located in /prelaunch/ to the /public_html/. I insert my admin credentials to the /wp-login.php/, but, when I select Log-In it forwards me to /prelaunch/wp-login.php/ and I receive a 404 – Page Not Found error.

Are there files that have contents that point to the original installation directory that I need to change? I am stuck and can’t login to the wp admin panel…

Thanks in advance!
