okay you arent helping but you tried but the download link only firicking leads to the latest download to 1.3
Then I don't know your problem. I just got on them just fine.
Also the Novetus itch.io site cites that they have a link for Novetus versions 1.2 and below.
If that doesn't fix your problem, trying searching for those versions on Internet Archive, I'm pretty much you'll find them.
internet archive isn't help. the only result is a 2007 client from that version.
Also how did you get it? The Internet Archive still isnt help.
