Ok.
Update your modpack to the newest Monster version 1.0.10, go into 'Edit modpack' and:
Disable: Biomes O' Plenty (416), Highlands, Thaumcraft(4.0.5b)
Enable: BloodMagic, SpecialMobs, and LycanitesMobs
Download the newest versions of Biomes O' Plenty(434) and Thaumcraft(4.1.0b), links are in the main post at the top.
Add them via the launcher 'Add Mod' in the Edit Modpack window. (make sure the new versions are in the enabled list)
You must also KEEP the betterstorage and xact mods (as they were removed in the 1.0.10 modpack), if you've lost them, come on mumble and we'll get that fixed.
IF anyone is having problems please come on mumble and I will troubleshoot the issue with you to get it resolved: voice.nfernalgaming.com
