OK. It certainly sounds like your system went south while Cocktail was doing its things. When we tried to run, it failed (likely for the same reason Cocktail was failing).

The "Unknown State" warning is phrased too severely -- it basically means your backup is not complete and (if you're using images) the image is still mounted. Nothing to be concerned about.

The unclickable window was due to the scheduling driver failing, again, due to whatever happened to your system.

Once you restarted, you likely cleared up whatever was wrong with the system, and you're now OK.

Hope that helps.
