 * rewrite error ussually mean that you already have this plugin installed and you
   are installing the plugin a second time. Go to your plugins and verify that you
   have only activated one instance of the plugin that you are having the error 
   with. Likewise varify that any plugin code and script for this plugin is also
   no duplicated in the same page.This may be your problem. I had a similar instance
   with another plugin giving me a rewrite fatal error and i fixed it when i found
   that i had duplicate plugins so i deactivate and delete one of the duplicate 
   and verify that there only one and it was activated and working properly since.
