Every time I try to open Minecraft using Forge 1.10.2 it loads, and then opens the Minecraft Launcher with the game output opened, and a very large message saying; 2016-07-26 20:18:36,673 WARN Unable to instantiate org.fusesource.jansi.WindowsAnsiOutputStream

I have only been able to play mods once, and all the other times it has showed this message. I have had Forge for at least two weeks and really want to play mods. Does anyonr else have this problem or know how to fix it? Is it my fault or is it Forge's fault? Please tell me if I can fix it or what's wrong.

NEI couldn't find CodeChickenCore. Make sure you have it installed.

 

In future, please post the full FML log (logs/fml-client-latest.log in your game directory) rather than a snippet of the console output.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

      Super Craft Bros REMAKE server! - Minezone Network (1.8-1.21)

      By VineFortuna · Posted

      Whether you are a fan of Hypixel Bedwars, SkyWars and PvP gamemodes like that, well you would enjoy this server! We have a very fun and unique style of PvP that a lot of our players really enjoy and we want to bring this server to more players like you! Yes you reading this post haha. Introducing, the Minezone Network, home of SUPER CRAFT BLOCKS. We've been working on this server for over 4 years now. Here is what we have to offer: SUPER CRAFT BLOCKS: This has 3 different gamemodes you can play, Classic, Duels and Frenzy. Each mode offers over 60 kits to choose from, along with a total of over 60 maps, allowing for various different playstyles on each map. There are also random powerups that spawn on the map which can include Health Pots, Bazookas, Nukes, Extra Lives and way way more! There is also double jump in this gamemode as well, which makes PvP a lot more fun & unique. You only need a minimum of 2 players to start any mode! Classic: Choose a kit, 5 lives for each player, fight it out and claim the #1 spot! Look out for lightning as they can spawn powerups to really give you an advantage in the game! Duels: Fight against another random player or one of your friends and see who is the best! Frenzy: Your kit is randomly selected for you, each life you will have a different kit. You can fight with up to 100 players in this mode and lets see who will be the best out of that 100! All the other stuff from Classic/Duels apply to this mode as well like powerups. We have 2 ranks on this server too, VIP and CAPTAIN which has a bunch of different perks for SCB and other things like Cosmetics and more.   SERVER IP: If this server has caught your interest in any way, please consider joining and you will NOT regret it! Bring some of your friends online for an even better experience and join in on the fun at: IP: minezone.club Hope to see you online!   SERVER TRAILER: https://www.youtube.com/watch?v=0phpMgu1mH0
