minemomgonemad · July 13, 2016

This is my first forge forum post, hope I did it right, I'm a mom regularly helping my 7 year old figure out this minecraft world, involves a lot of tears, frustration, but eventually smiles and fun...well we are in the throws of tears and frustration today due to a mod he wanted that runs on forge 1.7.10 and when we try to launch it we get this error:

HELP HELP HELP!!! Thanks in advance to the kind soul that does
