yogcraft start up crash [mac]

[ghost2794]

recently i haven't been able to launch my Yogcraft pack from the FTB modpack launcher screen. at the Mojang symbol it crashes, i have tried many things such as downgrading my java 7 to java 6 cause 7 isn't working for FTB and technic, i have also tried getting a thing thats called Feed The Mac which worked for a while but now is not maybe cause of the update to the launcher i'm not sure though. heres the crash report. \/ if anyone can solve this problem it would help a lot.

This error is caused by one of two things that I know of. The first is it is an ID Conflict with RP2 items. To fix that check out your console log and see if it has any reference to a 'block already occupied by' or something like that. If it does then check out this guide to fix the ID Conflicts.

The second is GregTech and where you have it installed, but I do not see GregTech installed so I doubt it is that unless you added it and it is not showing for some reason.
