GeoRAS error in clsMFloodDelineation

[chente]

Hello! i would appreciate some help with this error to which I can´t find any solution. I have tried it in many ways but i can´t solve it.

In Floodplain Delineation, Grid intersection, i get the next message:

Error in clsMFloodDelineation::CreateFloodplain
"esriGeoAnalyst.Grid Engine"
Could not open raster dataset from file.

I think this occurs when the processing is "clipping water surface grid with bounding polygon for profile P001"

I am using HEC-GeoRAS 4.1 and ArcMap-ArcEditor 9

Thanks in advance!!
