Blogs Widget/Avatars (BBPress) 3.5.2

getting this fatal error now with the blogs widget.. i have Avatars (BBPress) 3.5.2 and network activated.

Fatal error: Call to undefined function get_blog_avatar() in /home/xxxx/public_html/xxxxx.com/wp-content/mu-plugins/widget-blogs.php on line 160

i checked to see if there was an update for blogs widget.... and the instructions say:

Upload /blogs-widget/ folder to /wp-content/plugins/ folder on your site
Visit Network Admin -> Plugins and Network Activate it there.

but when i download the plugin it still has the old widget-blogs.php and not a /blogs-widget/

help?
