I need some help configuring the plugin, i am getting the following error, after saving settings with my DSN.

Fatal error:  Uncaught Error: Class 'Raven_Breadcrumbs' not found in /wp-content/plugins/getsentry-client/raven/lib/Raven/Client.php:94
Stack trace:

#8 /wp in <b>/wp-content/plugins/getsentry-client/raven/lib/Raven/Client.php</b> on line <b>94</b><br />

If I place the public DSN it dosen’t report to my sentry server.
