not too much help in here, people keep saying read eaq, y cant just answer..i tried to check it i dont know what it says...i maybe an idiot, but other people need some serious answers..just like when u ask somebody somewhere, u dont want to hear read the eaq.. its really hard for me to cope up with all these jargons, i just want to play mc with a mod i cant yet install coz im stuck with forge...great work anyway.

People say "Read the EAQ" for a reason. The Excessively Asked Questions (EAQ) tells you what to do in the most common instances of errors.

 

For example, the first line in the EAQ reads

 

java.lang.NoClassDefFoundException: net.minecraft.Launcher; Use a proper launcher. Mojang's/MultiMC/Magic Launcher are all known to work. Don't use sk89q's.

 

If you look at your logs that you posted above, it says

 

2012-12-13 22:03:45 [iNFO] [sTDERR] Exception in thread "Thread-11" java.lang.RuntimeException: cpw.mods.fml.relauncher.ReflectionHelper$UnableToFindClassException: java.lang.ClassNotFoundException: net.minecraft.Launcher

 

See how the EAQ can be helpful now?
