Trouble Reimporting Camera Clips

Hello, I have been wasting the last several hours on this maddening problem.

I am running FCPX 10.2 on an iMac (27-inch, Late 2012) with OS Yosemite 10.10.3.

I am editing a project with footage from my Canon7D. I finished editing my project, then realized (of course) that I couldn't share my project to a Master File, because I had accidentally ejected my camera during import and had been unknowingly editing from Camera Files.

That *****, but not a big deal, this ain't my first rodeo. I make sure the camera is connected (mounted, really, I use disk images of my CF cards).

Then I go to file>import>reimport from Camera/Archive.

I get the window that you're supposed to get, it says this:

I hit continue...

nothing happens.

I have been trying this is all kinds of different ways, making an archive from my camera files, moving the files themselves to library's original media folder, nothing is working. No matter what I do, the reimport option does nothing. I about to throw this computer across the room.

Any help would be much appreciated.
