Help, Arno

Just want to install animated jetways to airport.[FS2004]. Downloaded objplacer_aml_Installer (zip) and Objplacer_xml_084. Upon launching Got following:Error 53(File not found:mwgfxvb.dll) in procedureMDIForm_Load of FormMDIForm1. Ignoring this, next I got ObjPlacer XMl window with Available Objects:+ Defaut Library Objects;+ Effects; User library objects, MDL library ;+ Generic building.
I don't seem to be able to load "Gate.mdl", which is part of the dowloaded freeware.

Help, Arno !!!!
