So I've just downloaded forge for the latest version of minecraft currently,(1.12.2) and I've tried to start up my game with it and it never seems to work. I press play then about 10 secs later it shows the loading screen for a second and then crashes. Then it shows this error message (See attachment): The game crashed whilst initializing game Error: java.lang.NoClassDefFoundError: bnk
And when I press 'View Crash Report' nothing pops up. I have no mods yet and I need this mystery solved by January 22nd because I'm using a mod for one of my school projects.

I don't why it says pixelmon because I don't think I have it installed currently.
The Pixelmon mod you installed is for Minecraft 1.8.9, but you have Minecraft 1.12.2.

Post the crash report from your crash report folder in .minecraft.
Thanks I found it and it says this:

The Pixelmon mod you installed is for Minecraft 1.8.9, but you have Minecraft 1.12.2.
Where can I uninstall pixelmon?
You go into the mods folder and remove the file, either by deleting or moving to another folder.

Thanks for all the help. It works fine now.
