MultiDB plugin crashes on activation

I just uploaded MultiDB to my site, but when I activate it, the screen sticks to 'repairing databases' and all other pages show this:

Warning: require_once(../../wp-load.php) [function.require-once]: failed to open stream: No such file or directory in /home4/koc01002/flippedclassroom.ca/wp-content/plugins/multi-db/fix-db-encoding.php on line 14

Fatal error: require_once() [function.require]: Failed opening required '../../wp-load.php' (include_path='.:disappointed:usr/lib/php:disappointed:usr/local/lib/php') in /home4/koc01002/flippedclassroom.ca/wp-content/plugins/multi-db/fix-db-encoding.php on line 14

I've waited 20min with no luck, and had to remove the plug in via ftp for it to work. Is there something I'm doing wrong?
