Advertising Manager Error

I installed advertising manager plugin, when i go to add new code i get this error message below my input box.

Fatal error: Cannot break/continue 1 level in /home/bollixme/public_html/THINGSWHICHMATTERTO.US/wp-content/plugins/advertising-manager/class-admin.php on line 435

Can anyone tell me how to fix this.. Also, whats the best plugin one would use to put and manage ad’s. Any personal recommendation?
