Hello everyone i install forge in my Minecraft 1.6.2 with the forge installer and then i fallow many tutorials on installing Single Player Commands which leads to the same steps on deleting the META-INF folder inside the jar file, and i also did the other method which you only delete 2 files inside the META-INF folder except MANIFEST.MF, but i keep getting the same error:
Client> 2013-08-03 11:42:33 [SEVERE] [ForgeModLoader] For your safety, FML will not launch minecraft. You will need to fetch a clean version of the minecraft jar file
Client> 2013-08-03 11:42:33 [SEVERE] [ForgeModLoader] Technical information: The class net.minecraft.client.ClientBrandRetriever should have been associated with the minecraft jar file, and should have returned us a valid, intact minecraft jar location. This did not work. Either you have modified the minecraft jar file (if so run the forge installer again), or you are using a base editing jar that is changing this class (and likely others too). If you REALLY want to run minecraft in this configuration, add the flag -Dfml.ignoreInvalidMinecraftCertificates=true to the 'JVM settings' in your launcher profile.
Game ended with bad state (exit code 1)
