564819 Help restore mysql database from recovered hard drive

I had a "disaster recovery" company restore my server's hard drive. I had recovered everything from backups except the var/lib/mysql directory of root. I had a number of databases in root on the old server, that were used by multiple domains. I have moved one of those recovered databases to the root directory of a my new server. I am having trouble getting the database to integrate. The database shows up fine on phpmyadmin, but when used on the site, I get Warning: mysql_connect() function.mysql-connect: Access denied for user 'root' (at symbol)'localhost' (using password: YES) in /home/myusername/public_html/xxxxxx/[login to view URL] on line 44 It appears that there is a conflict with the root password between the two machines. The server is running Centos with cPanel. If you have serious experience working with servers and databases, and can have good feedback from those projects, I invite you to bid. There are about twenty databases that need to be installed off of the restored drive, but two of them are critical and I need to get them working withing the next twelve hours. You must be willing and able to start quickly.
