This message means that a CAD sheet requested a user library that was not found. The message probably appears because the root path for the library location was used.
To make DBDOC use the user libraries located in the modules, start from the Wizard and mark the user library query as omitted. If you do this, then DBDOC uses the same rules as WinCAD – it looks in the module folder for the library requested, moving up the tree to the root. This will catch the libraries where the INFI 90 system compilation finds them.
This message is cosmetic. If a shape is in the missing library, DBDOC_UNKNOWN_SHAPE.ERR will tell you.
