THIS PLUGIN IS NO LONGER SUPPORTED. There may be a new version in the future but for now…nothing.
If installing on WPMU/WP Multisite activate the plugin on a per site basis rather than the 'network activate'. See http://wordpress.org/support/topic/421758, http://core.trac.wordpress.org/ticket/14170, http://wordpress.org/extend/plugins/proper-network-activation/ if you need to do that.
Thanks to Tom Chippendale for a few pointers here and there.
