WiseOwl99 · February 20, 2014

Hi i have a problem with installing forge

i have downloaded 1.7.2-10.12.0.1029 and 1.2.7-10.12.0.1024

when i install them everything is normal

i start up minecraft and click the forge profile and press play now

it starts to update then closes the launcher then opens it again without starting the game

when i click play now again it does the same thing over and over

it shows this in the console
