.jsx giving the error "the command "copy" is not currently available

Hi guys,

I'm using since quite a while a script linking 3ds max render passes with photoshop. It basically complies the render elements of 3ds max in a psd folder. I recently bought CC ( I was using CS6 until now ), and since then, I have a new error sprounting when the scripts tries to compile the render elements ( basically this script compiles multimatte elements of vray into a single psd folder so that I have proper masks sorted ). Everytime photoshop seems to be compiling a mask, I have a window poping-up, saying me that "the command "copy" is not currently available", and frankly, I don't know at all what's happening and why.

I join you the screenshot of the error as well as the script I use, hoping that someone will be able to help me out.

Looking forward to hear from you,

All the best,

Hugues

Here's the jsx
