Basemap/Layer/Add Data problem

Ok so was in the middle of working on a project and the first basemap layer I added worked perfectly. I selected the .shp file and done. But now when I go to add data or a new layer, nothing is showing up. I get blank everything when I go to "Look in" folder option. I select the folder and nothing shows up. I also tried to open some other projects I worked on and the same thing occurred. Absolutely nothing comes up anymore.

Hopefully the image helps explain what Im talking about.
