Appointments+ conflict with Buddypress user permissions

There appears to be some conflicts between Buddypress and the new Appointments+ plugin.

I've done a clean install and checked pretty carefully. I keep getting
"You do not have sufficient permissions to access this page." on the
Settings tab for the Appointments+ plugin. Obviously that doesn't make any
sense considering I am the only user and Admin. This is a clean install. Only plugins used are Buddypress and Appointments+.
