Bp media crashes site

I installed your buddypress media addon, as soon as i activate it i get the error:
Fatal error: Class ‘BP_Group_Extension’ not found in /home/fantastc/public_html/wp-content/plugins/buddypress-kaltura-media-component/bp-media-group.php on line 5

i checked my buddy press settings and groups is enabled.
and the groups page is created fine.

im using latest wp single site, with latest buddypress

The BuddyPress Media Component will not be working with the current version of BuddyPress since BuddyPress was totally rebuilt after version 1.2.10 and is not having the classes the BP Media Component was using.
We are working on a new version which will support the current version of BuddyPress and will be releasing it soon.
