Okay, so latest update:

Did a factory reset (sans SD card). Put the blank, reformatted card back in, Aura started up with no problems. Did the setup via my PC and Kobo desktop, also with card in. Ejected Aura, let it update, then powered off and on. No issues.

I just reloaded the blank, formatted SD card with my library (exactly how it was before the FW update), ejected and let that process. Then I powered down and back on again.

And now I'm back to exactly where I was before--frozen on the square dancing.

So, I'm thinking it's not the card, but something in the FW that's causing this problem. It has no problem seeing the card or the books on it when it's plugged in after the initial setup with the Kobo desktop, or when it processed the card contents--as long as I don't shut it off.

It's that initial powerdown and up that seems to cause the problem.

In the meantime, I'm just going to have to load my books directly onto the Aura or try another card.
