I have just updated to the latest FTB Infinity version, 1.8.2, and I have also re added other mods. (mekanism, hexcraft, and a few more.) The problem is, whenever I try to launch my instance through MultiMC I get this error:
I tried reinstalling pretty much everything, but to no avail.

Note: I can launch it through the FTB Launcher, but I like to use MultiMC because I find it easier to manage instances. I am confused because I checked the box to track FTB instances. I find it strange that MultiMC fails to launch while FTB launches it fine.
