Error Messages in Members Directory

I am getting an onslaught of errors on my Members Directory where the chat buttons are suppose to be. They say:
"Warning: Creating default object from empty value in /home/yaznetx1/public_html/wp-content/plugins/wordpress-chat/lib/wpmudev_chat_wpadminbar.php on line 205"
How does one get rid of these, the whole page is jacked up because they're everywhere.
I am currently running Wordpress 3.5.2 and Buddypress 1.8.
