I am working with ArcGIS 10.0 sp5, ArcHydro Tools and HEC-GeoHMS, in a 64 bit system with Windows 7.

If I run Preprocessing|Fill Sinks from the GeoHMS toolbar I receive the following error:

"System.Runtime.InteropServices.COMException (0x80041098): ERROR 010007: Too many arguments.
ERROR 010299: Incorrect # of arguments.
ERROR 010067: Error in executing grid expression.
   em ESRI.ArcGIS.SpatialAnalyst.RasterHydrologyOpClass.Fill(IGeoDataset surfaceRaster, Object& zLimit)
   em ESRI.APWR.ApHydro.ArcHydroOp.FillSinks(ApLayers& aplayers, Boolean useIsSink, Boolean fillAll, Double fillLimit, ITrackCancel trackCancel, IGPMessage messages, String& exMessage)
Failed to execute (FillSinks)

But if I run Terrain Preprocessing|DEM Manipulation|Fill Sinks from the ArcHydro toolbar everything works fine!
Can someone please tell me what's wrong? Thank you.
