Material Penal No Responding

My Rhino material penal disappeared on my window, and no response while typing in the “materials” command. In fact, the material penal, environment penal, and texture penal all got lost. I checked my plug-ins and they are turned on. How should I fix this? Rhinocore is my default render.

please screen shot

render>current renderer

and tools>options>cycles

please post images of the above, and also please run the systeminfo command and post the result.

That list should be a lot longer. Are you running in safe mode?
