iv never encountered this problem until now, ever since i restarted my laptop to factory setting it started and i don't know how to fix it.
i am using windows 7 with a 64 bit java and every time i start minecraft with forge freshly installed, just before it finishes i get the message
"There was a fatal error starting up minecraft and FML"
"minecraft cannot launch in it's current configuration"
im scratching my head about this atm as i have no idea what to do so i would appreciate some help.
This is my 'ForgeModloader-client-0' no idea what any of it means...
