I'm a research scholar and using arcHydro for morphometric analysis. After 2-3 successful attempts, it is not working properly. I am unable to do catchment polygon processing after catchment grid delineation of my DEM. Everytime a error massage ''Hresult e_fail has been returned from a call to a com component" appears. i tried to delete all temp. files, related to my previous attempts and re-installed arcHydro but problem is unsolved.

Does anyone know what the cuase of this error could be? And solution of this problem also.
