Possible MultiMC incompatibility?

[luacs1998]

I use the MultiMC launcher, and when attempting to launch #193, i get this error:

 

 

Exception in thread "main" java.lang.IncompatibleClassChangeError: Implementing class

Is it my problem or Forge's?

MultiMC's problem, not ours.

Will have to ask them, because the other day I got an InvocationTargetException with just FML, asked on IRC, and cpw asked me to ask them.

I have spoken with them, Forkk came and bitched to me on Teamspeak, it's there issue, not ours.
