WordPress Embed Form Plugin: The plugin does not have a valid header

You may want to note that the name in the instructions is out of date. The plugin name has changed. Instead of "Embed Form" in the instructions, it seems to be "Jotform Online Forms – Drag & Drop Form Builder, Securely Embed Contact Forms ".

Also, activating this plugin from the Plugins > Add New page, doesn't activate. I get the message "The plugin does not have a valid header."

When I press "Activate" from the Plugins page in WordPress, it activates.
