I lost SolidWorks Commands in Windows Explorer

Previously I was able to right-click on a SW file in windows explorer and I could pack and go or rename the file right there.  After upgrading to 2011, the SolidWorks commands disappeared from the menu.  Now, to pack and go I have to open the part/assembly or use SW Explorer which takes a lot of extra time.

Does anyone know how to get the SolidWorks menu commands back in the windows right-click menu?

Thanks,

Paul
