multiple Macroscript (I think) errors

[AVATAREA]

I am in a very serious situation. all of the vray utilities like scene converter etc., have ceased to function. The error is similar on all. I have to supply a major file to a render farm by tomorrow, Monday 15 march and scene converter will not function either. Doing the whole scene manually is a potential nightmare. Any suggestions ?
Im running Max9 Vray 1.5 sp4 . Below is the typical error message I get
thanks in advance

Does it display the dialog box asking you whether you want to convert the scene (the problem seems to be there)? Anyways, you can just type in directly into the MaxScript listener this:

convertToVRay()

This will convert the scene without asking any questions.

Yes it does dislay the box. If I type the line you gave I get -- Type error: Call needs function or class, got: undefined.
The line in the macroscript error box is :

macroScript VRaySceneConverter category:"VRay" buttontext:"V-Ray scene converter" tooltip:"Convert all scene materials to VRayMtl and all raytraced shadows to VRay shadows" (
local res=queryBox "All scene materials and raytraced shadows will be converted to VRay materials and shadows. Are you sure?" title:"VRay scene converter"
if res then convertToVRay()
)

With the last line highlighted.
