It gives no crash report, but it says one of my mods needs mechanism, even though it's installed. Dont know if it's mechanism or another mod.
uhh the log is too big to paste, so you can download it if you want:https://copy.com/XGHXsZxIdpDOIz8z

looks like a problem with hunger overhaul, make sure its updated.

No, I updated and it didn't work, it also doesn't work when I remove it.
mabey it's a new log: https://copy.com/VIHPQ0bfVFKepyfg
In this one I remove hunger overhaul. And is this Mekanisms problem or should I be telling someone else?

its pointing to a plugin or something with hunger overhaul still, or maybe "iguana config"

im not really sure what mods you have, so a modlist would be good, but this isnt really the place for this.
technic would be a much bigger help, plowmanplow99 is always there helping

you also have a lot of ID mismatches, it all seems kinda messy, so it could be a number of problems.

i deleted all configs, and reinstalled all mods, took a while but it finally works, might have bin agricraft.
thanks for trying to help =D. XD just noticed I put minechem for the title, hope that did not confuse you
