I just figured it out! :D
After sifting through the installation files from the original K2 package, I noticed a file that was missing. I have no idea why it was missing, but it was. Just looking at the image, it's apparent that it was a CSS issue so I searched for CSS files and compared them to what I actually had on the server. Lone behold, I was missing the k2.css file that was supposed to be resident inside the /administrator/components/com_k2/css directory.
Thanks for the VERY quick response, William! And...thanks for befriending!!
