Hi, I'm getting the same problem for all my layers when I try to export them via the script. I've used the program before and it usually works, so now I don't know what I've done wrong.

Pro Spine version 3.7.94
Script version 3.8. (via the download)
Photoshop CS 2.

Here is a picture of the layout in PS. (attached).

Can you help me? Thanks!

Here's the errors.txt

That's the script I have.
But in the link you supplied (if I click on it and view it) it actually says the script version is 3.8.

var scriptVersion = 3.8; // This is incremented every time the script is modified, so you know if you have the latest.
Is that an issue?
