[Jake1003]

Hey guys i need help.  Now im trying to install forge  on a 1.6.4 server. So after i install forge i go and open forge universal then nothing happens it will add 2 files called  (ForgeModLoader-server-0) and (ForgeModLoader-server-0.log) but nothing opens no server hub opens nothing happens. Nothing opens then closes super fast. nothing happens at all.
