Hey everyone – we had some server problems this morning (as described by Brian here) that contributed to the cover art issues described in this thread, and which should now be resolved.
I’m going to close this thread, since the underlying cause of this problem should now be resolved.
That said, if you’re still having issues, please try rebooting your Core.
If you’re still having issues, create a new thread with these details, and we’ll take a look.
Thanks everyone – sorry for the trouble!
