Ness27 Posted March 24, 2020 Share Posted March 24, 2020 Delete: D:\Programs\CrafterLand Launcher\launcher Or the launcher folder, wherever you have it saved Re-install and update to new launcher version unknown1234 1 Quote Link to comment Share on other sites More sharing options...
Carthon Posted March 24, 2020 Author Share Posted March 24, 2020 I didnt install the launcher. I tried to but didn't let me getting that error. So i dont have that folder or such of. I did play with Twitch downloading the Dungeons, Dragons and Space Shuttles pack. For the launcher tho, if you check the error it says i need a certificate in order to download files from that URL. If i could see the launcher source code I could resolve it by myself but i dont actually know what certificate do I need or if i have to disable Java Security to download the files.
