Still fails to integrate.

I need, at minimum, your version of Thermal Expansion, and preferably the failure message printed to the log.

Sorry for the short post, thought I posted this originally.

Thermal Expansion 4.1.1-237
Forge 1566
FastCraft is installed.
Java 8

and I get the following; http://pastebin.com/7exWrL9u

Any luck m8 on how I can fix this?

This is actually a bug in the Forestry (and Misc) packs. There's a new update out for them which should fix it.
