Are you saying it crashed?

 

I don't know what that stuff means but it came up with that for the last 20 times.

 

Do you have any modded worlds? The same thing happened to me, so I went to %appdata% and .minecraft and deleted all my worlds and mods, and most recource packs. MC works fine now.

 

I do not have any modded worlds. I only have 2 normal worlds.
I use this server resource pack on a server which I am NOT going to say.
What is appdata?

 

Roaming, if you type in %appdata% in the Start box and press enter, it will pull up roaming, click .minecraft in the roaming window.

 

Start box? I know nothing about this junk sorry.

 

What kind of PC are you using?

 

A Windows 8 acer laptop.

 

Ok, see the lower right hand corner of the screen? is there a windows symbol in it?

 

1 just go in folder or files 2 and go to search 3 type in %appdata% 4 .minecraft will appear for windows 8 peeps

 

It is on the left. And yes I see one.

 

Run > %appdata% > .minecraft > worlds

 

Didn't work.

 

Uuuuuuuuuuuuugh! None of this is working!!! I searched up what BOTH of you said and it comes up with 20 options of the SAME data crap.

 

ill post screenshots brb (for windows 8 cuz windows 8 doesnt have run its a shortcut i dont remember)

 

So I should use the shortcut I created?

 

NAh didnt work what I just tried to do

 

What
