When I tried to activate this plugin, WordPress actually got into a deadlock! I clicked activate and it just wated infinite. Suddenly I realize that all my WP DB's couldn't be accessed. The plugin trying to activate, took all the server-time, so I had to get help from Hosgator-support. They could tell, that it was the plugin that blocked my DB's. We tried it several times. The same problem every time.
Really don't want to use plugins, that conflicts with your DB's and DB-servers.
