Hey, I need help with Flan's mod pack. It keeps on crashing right after the "Mojang" opening screen. I'm all ears, and please don't post saying the same has happened to you. Thank You!

Here's the message:



Minecraft has crashed!
----------------------

Minecraft has stopped running because it encountered a problem; Failed to start game

A full error report has been saved to C:\Users\LiL G939\Desktop\tekkit&customs\vanilla\crash-reports\crash-2013-07-17_15.05.11-client.txt - Please include a copy of that file (Not this screen!) if you report this crash to anyone; without it, they will not be able to help fix the crash

I don't know but I'll get the mod to see if I can help.

You have an ID conflict. Change the block ids in the flans mod config to free IDs.
