Catchment Polygon/Adjoint Catchment Problem

Hello all:

I'm trying to use ArcHydro to automatically delineate 8 research catchments.  Yesterday, it was working without any problem.

Today, I'm getting the following message whenever I try to run "Catchment Polygon Processing":

"-2147220982, the object has been deleted and is no longer valid. [xxdis]"

It then displays the catchment polygons anyway - I follow this by running drainage line (which works fine) but the next step, "Adjoint Catchment Processing" runs and states "it has successfully completed", but gives me an output with no data!

HELP!
