I am trying to use the DEM Reconditioning tool in ArcMap 10.0. Every time I have tried to use it I get the error "Object reference not set to an instance of an object." I have used different data from all over, and I always get the same error message. At first the coordinate systems for the stream file and the DEM file weren't the same, and I thought that was the source of the error. Now I have data that has the same coordinate system but the error keeps coming. Does anyone know what causes this error?

Thank you
