Admin panel not allowing "visual display"

I spent hours trying to find out why visual editor wasn't working. This specifically doesn't work on other users PC's, but is fine on my end, so it's hard for me to duplicate. I did log in on another PC that I have never used before and was able to duplicate.

I cannot get the Visual Editor or the "Content Composer" (from CMSMasters) to display. All I see is the 'text' tab.

And ideas? Need some editors to be able to edit the content. For staff members, I can grant access to the /admin panel.
