Acrobat Reader running but no windows displaying

I'm having a really weird issue with my Acrobat Reader in which the app seems to be running fine, and I can open pdfs (which appear under "Window" at the top of the screen when Adobe is in the forefront).  However, the windows simply are not displaying.  It is as if the windows are there, but invisible.  If I click on the right click the open app and click to "show all windows," I get something akin to the attached image. As you can see, rather than seeing the window, it simply shows the file-name with like a weird white slit.  Additionally, when I go to "view," most of the navigational and zoom options are greyed out.

I've uninstalled and reinstalled the app and still nothing.  I'm at a total loss as I have not been able to find anything on this issue.
