ArcHydro GP Tools--Export to Python Trouble

Discussion created by rechewjr80 on Jun 1, 2010
Don't know if this is the right forum but can't seem to find anywhere to post this.  I have a computer set up to run batch scripts at night.  It is running Windows 7 with 9.3.1.  I have a model which I exported to Python which one step involves assigning HydroID's to the newly imported data in a FGDB.  Everything ran fine except for the Hydro ID step (which I isolated to make sure it was the only problem) which gave me the error message attached. 

I tried running the same script on a computer running XP and got the command to run however the HydroID field was not populated.  Any help would be greatly appreciated.
