thats not the whole thing, just what I'm pretty sure is import.

cld u post a link to the pages where you got your mods?

This also happened to me. After i updated minecraft, i reinstalled my optifine mods and it wouldn't let me log in
Mods i got were
Optifine Light
Optifine Standard
Optifine Ultra

You need to edit the config for either IndustrialCraft 2 or Chocolate's better dungeon mod. Different blocks from both mods are conflicting

You're trolling right? You only need one Optifine mod... Try getting ONLY Optifine Ultra.
