Tekkit server 3.0.3 fatal error on launch

[hellow12327]

launcher/pack version: Tekkit 3.0.3

OS: Windows 7, 64-Bit

Java version: 7, update 4

Description of problem: Server gets an unhanded fatal error upon launch, seems to be a block ID conflict, but no one else seems to have reported this

I also have some Bukkit plugins running, but its just essentals and towny and such.

If you need a complete list just ask, but there is ALOT, and their all mostly command/perms plugins
