I was having a problem in wildcraft so I uninstalled it and used the master key to get it back but it was still the same so I uninstalled it again but I forgot to get a new master key and I tried putting the old one in and it said master key could only be used once per 12 hours and I don't know if it will be fixed in 12 hours or not. I'm so scared and freaking out because I spent loads of money and work into that game and got half the mystics and even had a YouTube channel for wildcraft and now it's all gone. Please tell me if I can do anything to get it back. I'm so so so so sad I'm crying and I can't do anything?
