Hi everybody,
I have a trouble trying to rebuild network after editing the feature class. I've just added a feature in the feature class, that is used in the network. I push "Build network" button after ending edit session, but the message appears:

Build network dataset failed
The logical network is of an older version and does not support the requested functionality

In ArcGIS 9.3.1 there were no problems with this. It build a network and calculated the new route. What's wrong with ArcGIS 10? (The database used is created in the 10th version).
