It's looking for the in runtime class but it doesn't find it. Do you have the latest versions of mekanism?

I figured out my problem, it doesn't want to work for some reason with any of Reikas stuff, which makes me sad because I really wanted to try them out. But ehh I would rather have Mekanism then Reikas stuff.
