So, long story short, I've tried to install a login interface from another forum.
It has folders:
lib, login, root, uiscript, locale_game and locale_interface.
I've updated everything in each folder, and created eix and epk login files, added them to pack, added them to index, but I get this error:

The interface is here, on mega: [Hidden Content]
Edit// FIxed it. I had to add login to ETC.
