 * I am having the same issue with version 1.3.1 and wordpress 4.2.2. I install 
   the plugin and when I go to activate it I get the “Plugin has Invalid header”

 * I was able to activate the plugin from my plugins list. I could not activate 
   it from the install screen.

 * Hi hitpdnewz and hayden69,
 * We found the cause of the problem and fixed it immediately in the current (1.3.1)
   version of the plugin.
 * We made a little mistake during the release of version 1.3.1 which made WordPress
   have trouble activating it from the Install Plugin screen. Luckily it can still
   be activated from the Plugins screen.
 * The problem has been resolved and the plugin can now be activated directly after
   activation.
