Groups

I have been trying to get groups fully functional but i'm not having much luck. I can create groups just fine and post new topics, however i can't view the topics cause i get this: [L[Access denied]] I have memberships enabled and these features have been made available to a certain status, i realy need help with this...i haven't found the answer yet so i hope to get one here. You can see it here: http://buzznconnect.com Username: Bozo Password: admin2217 here's the URL to one of the groups: http://buzznconnect.com/groups/entry/Test-Group Any help is appreciated Thanks
