i've narrowed it down to a conflict between Pam's HarvestCraft and Millenaire, even though the official wikii says they're compatible.
I'm using Minecraft 1.5.1, Forge 1.5.1, pam's HarvestCraft 1.5.1 but Millenaire 1.5.2
Could that be a problem? I couldn't find a Millenaire 1.5.1 download so I'm using 1.5.2, but it works fine without Pam's Harvestcraft.
could any brilliant mind here offer some assistance? :)
Is there a 1.5.2 Pam's Harvest?

Millenaire for 1.5.2 is only for 1.5.2. You will have to update to update to 1.5.2 and your other mods to 1.5.2 if you can't find a millenaire 1.5.1 download.
EDIT: I just saw you said it worked fine without pam's HarvestCraft, so in that case i don't know. My only guess is that you should update to 1.5.2.
EDIT 2: Forge 1.5.1 might be compatible with millenaire 1.5.2, but pam's HarvestCraft might not be.
