so i have this server made on aternos(going on tlauncher) and i downloaded skyfactory 4, at first it looked like it would work i addded all configs and what not, and when i start to play the game it stops and says "Fatally mising registry entries".Is it because of the login thing on the left corner? Because i dont really know how to ling to it.. (what is this btw)
