There was nothing in that thread that helped.

I will look in that thread to see if it helps. Both of your suggestions were already being done.

Josh,

I've posted several "solutions" to Arc Hydro problems at ArcHydro Problem Solvers‌. You can peruse this for other solution ideas.

The "HRESULT E_FAIL" type error could be due to two things (my best off the top of my head guess).

* Having your project files on a server. Put them on your local drive - runs faster and with fewer errors like this.
* Put as much of your data as possible in geodatabases. They are more stable than regular shape files.
