.DWG and .DGN will not drop in to ArcMap 10.2.2

Question

I am attempting to bring in Microstation data (.DGN) into a working ArcMap file. Every time I attempt to drop the data in the map I get the following error message... (Error could not open the specified file)

The original files were .DGN, I had a friend convert them to .DWG and have received the same error. I have also attempted to use the {CAD to Geodatabase} tool on both file extension types and, once again, get the same error message when I try to add the data to the map.

Any suggestions?

I'm pretty sure you have to use the add data button.
