With the current development version I am not getting this error. You could try 
running with the
nightly build (which is pretty solid and close to being released):
http://www.unidata.ucar.edu/downloads/idv/nightly/index.jsp

Or you could try adding this jython to your local library:

def layerDiff(grid, top, bottom):
   return DerivedGridFactory.createLayerDifference(grid, top, bottom, None)

Go to Edit->Formulas->Jython Library and past the above code into your local 
library and hit Save.
