I recently upgraded our Drupal site to 7.56.  I immediately saw that our md slider dissapeared.  The module files still exist in the sites/all/modules directory, but the module does not display on the administrative modules page.

I am trying to use the this slider version md_slider-7.x-2.22.zip

We had been using the slider with the purchased theme (Construction - Construction, Building Business). Please help gyuide us in getting the slider setup and working again.
