Help on InDesign script to convert images to PSD - can't read file locations on networks

Hello, 

I have a script which can convert images to PSD from InDesign via Photoshop. 

Photoshop however is not able to read the image which indesign is trying to send to photoshop. 

It must be something to do with the next work. 

I also am not convinced that the script is able to access the output folder properly too... 

To be honest I have no idea what is going on - script works fine on local but on a network the script just fails at passing the image to photoshop.

It is not a privilage problem as everything the script is doing I can do by hand i.e.  read and write to the following locations. 

The script funtions fine it just cannot get the file in question 

Any help would be good, 

Many thanks, 

Smyth
