Using HEC-GeoHMS, I am unable to subdivide my subbasins using the Subbasin Divide tool. Anybody else experienced problems like this?
When I select a point on the existing stream, I get the following message:
"Failed to extract FlowDirection/SourcePoint Grid" I click ok and get the next message:
"doRiverSplitPoint, System.Runtime.InteropServices.COMException(0x80004005): ERROR 010024: Error during conversion.

ESRI.APWR.HECGeoHMS10.HMSFunctions.doRiverSplitPoint(Hashtable & htParams)"
When I attempt to use Subbasin Divide on a grid cell inthe flow accumulation grid that is not in the current stream network, I get a similar message to the second above:
"doRiverSplitLine, System.Runtime.InteropServices.COMException(0x80004005): ERROR HRESULT E_FAIL has been returned from a call to a COM component.

I've had similar messages returned when attempting to use the Batchpoint method for delineation and the Subbasin Divide by Maximum Area tool.
