Today I was trying to install inficraft, and using magiclauncher, all the mod statuses seem to be ok however when I launch minecraft i get this error:

java.lang.IncompatibleClassChangeError: Implementing class

Please help me resolve this, I am using minecraft 1.4.7 and on a lion mac.

Forge never even sucessfully launched, so the forge config and log files were never created.

I never tried installing forge without any other mods, however the other class files I installed on top of forge made just minor adjustments and I am using forge 1.4.7-6.6.0.499

Yes, i have done both but through terminal, so im not sure if it worked or not.

So what, noones helping me now? This fourm is pathetic.

Minecraft forge has one error even if I use magic launcher I am using the latest version I am pretty sure and it still has 1 error

I am using
minecraftforge-universal-1.4.7-6.6.0.497 (2).zip
