Recently I moved my Wordpress Install with CiviCRM over to a new server. I changed the path location in civicrm.settings.php file to reflect the new location. The front end of appears as if nothing is wrong but on the admin dashboard this appears:

Warning: require_once(/CRM/Core/ClassLoader.php): failed to open stream: No such file or directory in /home/xxx_xxx/public_html/wp-content/plugins/civicrm/civicrm.settings.php on line 399

Fatal error: require_once(): Failed opening required '/CRM/Core/ClassLoader.php' (include_path='.:/home/xxx_xxx/public_html/wp-content/plugins/civicrm/civicrm/:/home/xxx_xxx/public_html/wp-content/plugins/civicrm/civicrm//packages:.:/usr/lib/php:/usr/local/lib/php') in /home/xxx_xxx/public_html/wp-content/plugins/civicrm/civicrm.settings.php on line 399

If I deactivate CiviCRM, everything else appears to work fine, but I need this to work for this site. Any and all help is greatly appreciated!

Looks like you've a couple of hangovers! These are usually in the CiviCRM Administer > System Settings > Resource URLs, and Administer > System Settings > Directories pages. Update those, clear cache, and you should be good to go!
