HEC-GeoRAS HydroID error

I recently started working with HEC-GeoRAS to do a dam break analysis. As I'm editing the geometric data, I have encountered a problem: every time I finish drawing a feature (does not matter which kind...river centerline, banks, cross sections, bridges...all) I get the following message (it´s translated from spanish because my windows is in spanish):
"GetUniqueId=-214...a lot of numbers, The Microsoft Jet database engine cannot find the table or the entry query "HydroIdTable". Make sure that it exists and its name is written correctly"

Well, after this...all seems ok, but the HydroId field in the table of attributes is populated with -1 for every feature. As this field is used later to create links between the layers, I have a strange feeling that this is going to cause me problems.
Anybody knows what's happening?

PS: I work with arcgis arcinfo 9.3, hec-georas 4.2 for 9.3 and hec-ras 4.1. I also have archydro (a beta version) toolbar installed.
