Moving website to root directory gone wrong

Dear all,

Thank you in advance for your help. I made the mistake of assuming that it would be easy and now I am stuck.

I created a wordpress website in a protected subfolder “/wordpress” while the main html site was running in the root directory. Once I finished the wordpress website, I changed the URL in the General Settings within the Admin Panel. Trying to save those settings I already received the first error message that I unfortunately did not save. Hoping that everything would be fine, I then moved the website from the /wordpress folder to the root directory, after I had previously removed the html website.

If I now try to access the wordpress website in the root directory, I get the following error message:

Warning: require_once(/home/content/72/26125231/html/wordpress/wp-includes/load.php) [function.require-once]: failed to open stream: No such file or directory in /home/content/72/26125231/html/wordpress/wp-load.php on line 42

Fatal error: require_once() [function.require]: Failed opening required ‘/home/content/72/26125231/html/wordpress/wp-includes/load.php’ (include_path=’.:/usr/local/php5_3/lib/php’) in /home/content/72/26125231/html/wordpress/wp-load.php on line 42

I would be eternally grateful if somebody could help me with this, as I put a lot of work into the website and I am panicking, afraid I might have lost it all.

Thank you,
Kilian
