Minecraft: Que significa esto?

Hace un tiempo decidi desinstalar Minecraft y lo borre completamente, hace unos dias lo quize instalar de nuevo con el magic launcher 1.3.1 y con la version recomendada de la pagina de forge, para aclarar tengo java 7 porque dicen que el 8 trae problemas y lo tengo con la version 1.7.10, pero cuando lo abro me sale esto:

*** MagicMinecraftLauncher 1.3.1 ***

There has been CRITICAL TAMPERING WITH MINECRAFT, it is highly unlikely minecraft will work! STOP NOW, get a clean copy and try again!
[18:39:26] [main/ERROR] [FML]: For your safety, FML will not launch minecraft. You will need to fetch a clean version of the minecraft jar file
[18:39:26] [main/ERROR] [FML]: 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.
