Issues with Importing Rig from Photoshop

Greetings,

I’m having issues importing a .psd layered rig into Toon Boom Harmony Advanced. Most up to date version, new scene.

Issue is that it is saying that it can’t read the file. Is there a way to fix?

I’ve tried restarting both PS and TB, importing single, JPEG layers works fine.

PS file is fresh, made this last week, and shouldn’t be corrupted, still works fine within the PS program.

Each layer is within its’ own grouping.

It’s not an overly large file, I’ve managed to import larger just fine so not sure what’s going on with this particular one.
