Fatal Error

Everytime I activate the plugin I’ve gotten the following error messages:

Warning: require_once(/FlipIncludes/FlipShortcode.php): failed to open stream: No such file or directory in /home/xxxxxx/public_html/wp-content/plugins/countdown-flipclock/FlipClock.php on line 42

Fatal error: require_once(): Failed opening required ‘/FlipIncludes/FlipShortcode.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/xxxxxxx/public_html/wp-content/plugins/countdown-flipclock/FlipClock.php on line 42

I get the same error message regardless of whether I download the plugin from the Repository within WP or download and upload the plugin manually.

I also get the error when I deactivate all other plugins.
