I have asked this question before, but this is different.
I am currently using the new Minecraft Launcher 1.4.4. I am using 1.6.4-Forge9.11.1.965 with some Forge mods installed:
[1.6.4][Beta-V6.1]DivineRPG
DrZharks MoCreatures Mod v6.1.0
Galacticraft-1.6.4-2.0.13.1063
Galacticraft-Planets-1.6.4-2.0.13.1063
GollumLib-1.0.0_for_1.6.4
idfixminus-1.6.4-1.0.0
MicdoodleCore-1.6.4-2.0.13.1063
More_Pistons-1.5.0_for_1.6.4
theEther2.9.6
Recently, I had an ID mismatch with DivineRPG and Mo' Creatures:
java.lang.IllegalArgumentException: Slot 701 is already occupied by net.divinerpg.block.ModBlock@7405e77f when adding drzhark.mocreatures.block.MoCBlockLog@40a7c0cc
I thought that IDFix Minus would fix this, but it did not for some reason. I changed 701 to 1012 and started Minecraft. I clicked play, and then it loaded. I waited for Minecraft to show up with the Mojang logo, but it never happened. I looked at Task Manager and javaw.exe was still running. I was perplexed at how this happened. I changed 1012 to 1013, then 1013 to 7777, but still no luck. Is there another solution other than deleting Minecraft?
