The Site Wide text change, cant access dashboard

The error message I get is:

Warning: preg_replace() [function.preg-replace]: Unknown modifier ‘/’ in /home/donmcint/linkedbees.com/wp-content/plugins/site-wide-text-change/site-wide-text-change.php on line 436

And its repeated like 300 times and I can´t access the dashboard. How can I fix this??

Thx, Donald.
