GeoRAS ERROR..HELP!!

Question

Hey everyone,
I am generating a inundation map within HEC GeoRAS.  I have my GRID topo data into ArcGIS10 using GeoRAS 10, and have also successfully imported my HEC-RAS model on-top of the topo data.

I go to run my "Ras Mapping" Water surface generation, and everything goes fine.  My problem occurs when I attempt to Delineate my Floodplain.  Here is the message I get after it runs awhile and then crashes.  (see attachment for error message)

Anyone have any idea why I am getting this error?  I have tried running the Ras Mapping with a TIN ground surface with the same error.  Any ideas??

Thanks!

Why don't you consult the experts: Dr. Maidment or Dan Snead @ dsnead@mail.utexas.edu

I see from your error dialog that the directory path has a dash in it.   this could be the cause of your error.

Unless that is something new to Arc 10's geo-ras it shouldnt be.  My company's entire project structure is set up as yr-proj# and we have never had an issue with Geo-ras that wasnt human error.  Then again, we dont use its built in mappers and instead use the methods I listed before.

If it screws up with dashes in the file names our IT department will be very unhappy
