Problem with ADO and Delphi 4

I have a BIG problem.
When I import "Microsoft ActiveX Data Objects 1.5 Library (Version 2.0)"
into Delphi (using import type library) and then trying to compile (I
haven't written any code) I get the following message:

Overloaded procedure 'Set_ActiveConnection' must be marked with the
'overload' directive.

What the hell does this message means.

Please help me.
