Can't add SCENE card to Apple Wallet

SCENE recently sent me an e-Mail stating my rewards membership number had been changed. So I've had to delete my old SCENE card from my phone. I've logged into their website and confirmed my account is accessible to me with the new membership number, but now after deleting the old card off my Wallet, I can't get it back.

I downloaded the SCENE app, logged in with my current information, and went to use the option to add the SCENE card back to my wallet, but it won't let me. It says "Unknown Error - Request failed: not found (404)".

Anyone know what I can do to get this worked out?
