I still use this software everyday. It seems that my login still works fine but new users do not work anymore. So I am very happy that it works for me.
I also have a fully updated build of the latest version and for new users are still updates required which are not possible anymore.
I heared the creator now works for Hypixel Studios the creators of Hytale but it would be great if this tool can become open source under a MIT or similar license which would allow other software developers like me to make a new overhaul for this software and get it back available to the public.
So I hope Sparklin Labs would consider open sourcing this like they did with Superpowers. As there is so many people still wanting to use this.
