Auto-Update install fails with RMA_CDKEY empty error

When might that be? I haven’t even tried to download any WIPs since people started reporting this inappropriate behavior here. I tried the last WIP I had over the weekend and it wouldn’t load because it expired.

ALSO: do you think I should delete the one I’ve got before trying to install the new one when it’s released - or do you think I’ll be OK just installing the new one over the old one?
