Previously saved locations turning red.

I would suggest seeing if you can start fresh by deleting the files on the new card and then make a little test setup and save it to a few spots and see if the issue persists. It's possible that if the card you copied from had bad data on it then copying it to the new card would undermine the experiment.
I see the files arrived in the support inbox and I'll try and get Steve to take a look at them as soon as he's available.
