I am trying to run a custom modpack server for 1.5.1. This is the error I am getting: http://pastebin.com/B7bghuAA
It happens when I add more than a few mods. I spoke to someone who said that it was a mod that requires other mods to work ie Gregtech needing IC2. However I have double checked that this is not the case since I can install Applied Energistics yet I can't install forestry or IC2 which have no other required mods. I have been at this for a couple of days now and I am getting quite frustrated. Any help would be appreciated.
