I seem to be having a issue where inventory tweaks crashes the forge loader upon half way through the installation. I am using the 1.7.10 version and at first I thought it was thaumcraft causing my game to crash. But upon process of elimination i found that the Inventory tweaks mod was the reason for my game crashing. Is there a problem with the 1.7.10 version? I tried previous updates of it including the 1.5.7 before the 1.5.8 update. I cannot use the 1.8 version of IT right now due to the fact that the other mods im using still havent updated to 1.8. I've tried multiple downloads to fix the issue but each of the files seems to have the same crashing issue. Is there another mod I'm supposed to download with IT along side? Like an API or GUI?

This is the crash report if it helps any....

That's generally indicative of an install problem (particularly some annoying launchers that try to overlay things into the main jar instead of installing mods properly), or a conflict with another mod.
