V4 Clothing Morphkit in Poser 9 - error

Hi All

I've upgraded to Poser 9 and have installed the V4 Morphkit by Netherworks.

However when applying a magnet and using the Python scripts window provided (clicking on any of the buttons) I get the following error message -

NULL (or empty) script name passed to PEPythonEngine::DoScript()

I can use the buttons by going to: Scripts, Netherworks, Clothing Morphkit 3 and these all work.

Does anyone know why this would be happening? It's doing it on both my PC and Laptop.

I've also updated my Poser 9 to SR3 and that doesn't help it.

Specs - Running Poser 9 on Windows 7 - 64bit

Really hoping someone can shed some light.

Cheers
