[Custom modpack]Minecraft (1.6.4) crashes on startup whenever I try to add ICBM

[Guest]

Hello,

I have made my own custom modpack, including some mods.
However, whenever I try to add Calclavia's mod ICBM (no matter which version, wether it's a recommended or development version) and press "Play", the launcher will start the client, but immediately closes aswell.
I have had this problem with adding the Calclavia core and Atomic science before aswell. However, I solved this by just using the Calclavia core and Atomic science mods from the currently existing Tekkit modpack, and problem solved.
However, Tekkit does not use ICBM, so I have no other choice but downloading it from their site, but then it always crashes.
I have Calclavia core and Universal electricity both installed, which are the requirements.

Any useful help will be appreciated!

Calclavia does not always ensure that all of his mods work together when using the latest builds of each. Your best bet is to hit his IRC channel and ask which ones work together. You can also do some trial and error debugging to figure it out on your own.
