I fully maintain and support this package and will provide you with all the help I can as part of the license you purchased.
I CANNOT, however, offer help and support for CKeditor plugins that have issues or bugs. For those, you will have to ask the plugin's developer directly.
Although CKeditor Plugin Installer (or Pluginator as I like to call it) is built to make things as easy as possible, you still have to learn to use it.
I made a series of video tutorials for you to watch that will take you from beginner to expert in no time.
Due to the way this package works, CKeditor plugins it installs will not appear in Concrete5's normal dashboard page for CKeditor plugins
This is nothing to be concerned about and you can fully manage them from the package's own dashboard page.
