Broken integration with CB

Komento breaks the site... it seems to be related to an inability to integrate with Community Builder. On the broken pages this is what I get:

<img src="/<br />
<b>Fatal error</b>: Class 'KomentoProfileDefault' not found in <b>/home/xxxxxxxxx/http://xxxxxxxxxxx.com/administrator/components/com_komento/includes/profiles/adapters/communitybuilder.php<;/b> on line <b>45</b><br />

I don't know if this is related to the other issues mentioned on the forum recently but I have had to disable all comments until this is fixed...
