I am using ArcHydro14 in ArcMap 9.3.  I am trying the run the ???basin length??? watershed processing tool.  I keep getting the message below:

System.Runtime.InteropServices.COMException (0x80041098): ERROR 010067: Error in executing grid expression.  DIRECTORY FULL at ApFramework9.ApUtilsGenClass.extractByPolygon(IGeoDataset pRaster, IPolygon, Int16 nBufferDist, Double ThresholdPCT) at ArcHydroNet.BAsinLength.BasinLengthWk(ApLayers apLayers, String title, String& msgReturn)

This is baffling to me because I was able to run this tool on the first three subwatersheds my shapefile feature class.  I'd appreciate any advice you have on how to get past this rock that I've run into.

Thank you,
