That was the full log. Or at least everything Minecraft gave me. Just in cast I have copied this directly from the error report I just created when I tried to log in to my world. I get no other information than this.
I have just installed Minecraft Forge for 1.7.10 and I am trying to run the Minecraft Millenaire mod. I used the 1.7.10 forge installer and then installed Millenaire manually in the mods folder. When I start forge it informs me that there are 4 mods running (one being Millenaire) and will allow me to get all the way to creating a world. Once I hit the "create world" button it goes through to usual "building terrain" and etc. After this it says "Shutting Down Internal Server" sits at this for about 5 minutes then gives me this error: From what I can tell it looks like I simply logged out even though I haven't even gotten into the world yet. Since it actually loads Minecraft up, and registers that Millenaire is loaded I'm not sure where the problem is. -Note: Yes I know I spelled Millenaire completely wrong in my world name. I couldn't remember how to spell it at the time.
