HELP! - AttributeError: 'JoinImageWithAlpha' object has no attribute 'join_image_with_alpha'

[cerrec]

The basic workflow processes fine, but when it hits the node Layer Diffuse Decode (RGBA), it stops with this error:
AttributeError: 'JoinImageWithAlpha' object has no attribute 'join_image_with_alpha'

I have no idea what to do. Any help would be deeply appreciated.

Here's some info about my system:
