Clockwork Nero

I have the same problem, do you know what they did to solve it? I looked at both modular powersuits and mekanism, but I didn't see any item ID conflicts. Looking in the Forge logs I don't see any errors (though granted I'm rather new at this), and the server with all the same mods starts without any problems. It's just that the client goes right to a grey screen and I can't figure out what's wrong.
