Hey im trying to launch the game/mod and it says The game crashed whilst unexpected error
and i have the forge mod 1.7.10 and no other mod in the mods folder and i dont know what to do

Game Crash log?
can be helpful.
win + R and paste this %USERPROFILE%\AppData\Roaming.minecraft\crash-reports
then get the log with the correct date :)

Closed due to

1. Inactivity
2. Us not supporting the mod anymore
