whenever I load up a custom modpack on the Technic launcher it loads all the mods but as so as it pops up and say setting up forge environment then it says fatal error on FML I don't know want to do
ok first of all you need gui api and custom spawner gui api goes into coremod other goes into mod mo creatures goes into mod folder and you have the wrong version of it 5.0.7 is for 1.5.1
Well it starts like this goto your %appdata% then click roaming then .minecraft after you have to see if the mods go in coremods mods or jar like minecraft forge goes to jar
