Error while catchment polygon processing

When I use ArcHydroTools I cannot perform the step "Catchment polygon processing".
First I get the message "5, Invalid procedure call or argument". After pressing ok I get the message "Error occured while Catchment poygon processing!". All the previous steps work.

I have seen on older ESRI forums that other people had the same problem. There were several suggestions on how to solve this problem. I have tried to reinstall Hydro Tools, emptying the Temp-folder, checking that all the folder names in the project are shorter than 8 characters, the Spatial analyst is activated in ArcMap and so on, but nothing works.

Is there anyone who have had this problem and know how to solve it?
