I'm using Minecraft forge (1.7.10) and all my mods including Optifine is 1.7.10 also, nothing wrong there. So what's up with this message.

The Minecraft game output calls it "Fatal"

This is the message before that one if that helps any...

FML
IndustrialCraft 2 Error

The IC2 config file contains an invalid entry for balance/recyclerBlacklist.

Invalid value at line 63 (recyclerBlacklist = minecraft:glass_pane, minecraft:stick, minecraft:snowball, minecraft:snow_layer, minecraft:snow, IC2:scaffold).

There is no item matching IC2:scaffold.

I uninstalled Industrial Craft 2 from my mods folder and that fixed it, there is some kind of bug with Industrial Craft 2 for 1.7.10.

Did you edit the IC2 Config?
