 * Your plugin is great! I have only one problem: When I try to activate the plugin
   after successful installation, I get the following error message: The plugin 
   has no valid header. (To German: Das Plugin hat keinen validen Header.)
    Do you
   have any idea what could be the problem?

 * Hi Burkhard,
 * We recommend you try to install the plugin again. Maybe it was temporary.
 * Best regards.
