I was receiving a fatal error and syntax error when I attempted to activate this plugin. I figured out how to resolve this issue based on other users' comments, but I don't know how to delete this support request so I'll just include the work-around below. Hope this helps others out there!
For others who receive a fatal or syntax error when attempting to activate version 1.1, you have to upgrade to PHP 5.3. If you have a security plugin installed such as Better WP Security, you will need to temporarily allow scripts and users to write to your .htaccess file. Once you allow, then uninstall and reinstall the plugin. It should activate now without a problem. After successful activation, you can go back and lock your .htaccess file again.
