To troubleshoot this, first download a fresh copy of the vBulletin ZIP file from the Members Area then reupload all the original vB non-image files (except install.php). Make sure you upload these in ASCII format and overwrite the ones on the server. Also be sure to upload the admincp files to whichever directory you have set in your config.php file. Then run 'Suspect File Versions' in Diagnostics to make sure you have all the original files for your version and that none show 'File does not contain expected contents':
Admin CP -> Maintenance -> Diagnostics -> Suspect File Versions
