VBscript error with MS Agent Control

Getting an error on line 11 of this program.  I have loaded the Agent software properly.  Thanks for any ideas.

Set MSAgent = CreateObject("Agent.Control.2")
'
If IsObject(MSAgent) = False Then
   MsgBox "Microsoft Agent is not installed."
   Quit
End If
'
MSAgent.Characters.Load "merlin", "merlin.acs"   ' <--- getting error on this line
Set Merlin = MSAgent.Characters("merlin")
'
With Merlin
    .MoveTo 600,100
    .Show
    .Play("Read")
    .Speak("Your message is ready for you to read.")
End With
