 * Installation failed with Uji Countdown 2.0.3. Error “Plugin does not have a valid
   header”. This issue has not been resolved. Force activation may show that the
   plugin is activated, but the shortcodes do not work. Nothing displays.

 * The last version fix the issue “Plugin does not have a valid header”
    Did you
   do update or new install? What version of WP do you use?

 * Hello ujimoto,
 * Your latest version of the plugin still has some issues. As I indicated before,
   I am using version 2.0.3 of the plugin with WordPress version 4.1

 * I had exactly the same thing with the latest version. Go into your settings/permalinks
   and click on save then try and activate the plugin, it should work. Weird but
   effective.

 * I hope is fixed in version 2.0.4
    Please report here if still having this issue.
