I upgraded my FTB version to 1.3.1, put some mods(Damage indicator, Flan, Balkon's, Millenaire, Customnpcs, etc.) and deleted some mods(ModularPowersuits, Numina, Natura, etc.). But it is not launching without any crash reports or message, just says 'Unable to Launch.'. My Java versions is 8 and I use Windows 7. I am totally noob at Java, so I couldn't figure out the problem exactly. I tried everything to solve this, but it is just saying unable to launch. I will post my entire FTB logs, so if you have any solution about this, please, please leave me that solution ;(
