Only the default skin in preferences

Hello,
I just installed OpenPHT. It works but I’d like to use a different skin. From what I read in the forum the Aeon Nox skin should be available in preferences? When I go to the skins menu the only available skin is OpenPHT 1.6.1. No option to download or update anything. How to I install the other skins?

Thanks

Upgrade to 1.6.2. If it’s not there after that, you have some SD Card corruption and will have to wipe and load OpenPHT from scratch.
