Importing into wp

When we are trying to activate the demo importer plugin we are getting this error: Fatal error : Cannot declare class OCDI_Plugin, because the name is already in use in /home/toptechatlanta/public_html/wp-content/plugins/heacool-demo-installer/heacool-demo-installer.php on line 21

Can you please help us fix.
