Hello i was curious can i still use my early access pass key(key received via email on 10.09.2017) because it seems i can't download nite team 4 universal launcher ?
that link should be dead indeed, you'd need to get the new version from steam (you might need to ask anashel about this), and then insert the code from there
try following the steps from this post: https://forums.aliceandsmith.com/threads/read-this-for-priority-support.4827/ anashel, or any of the other devs who can help will help you as soon as they are able to (note that its weekend now, so it might take some time till they receive it)
