Minecraft Forums

So I just deleted and re-installed Minecraft, Forge, and a few mods I want to play with. After downloading each mod I opened my Minecraft to make sure it worked. After the last one I downloaded, when I open Minecraft it crashes.
The mods I downloaded are:
Not Enough Items
Zans Minimap
Biomes O Plenty
RedPower 2

RedPower 2 was the last one I downloaded, so I'm assuming that's why its crashing, but I've used all these mods together before, so I'm not too sure what's making it crash. Its crashing before it even makes it to the Minecraft Title Page.

Here is my crash report:

If anyone could help me and let me know what I can do to make it work, I'd really appreciate it!!

Does it work properly if you remove the RedPower 2 mod?

Yes it does. I just tried opening Minecraft with only RedPower 2 downloaded, and it crashed as well, so it must have something to do with RedPower 2 itself. I've used this mod before, but maybe I downloaded something wrong? D:

Here's the crash report from using only RedPower 2:

Actually, I think I'm just going to give up on RedPower 2. I was only using it because of the ores/gems it added that can be used to make tools. I'm just going to try to find a different mod that does that, if anyone has any suggestions of mods that add ores, please message me!!! I made a topics on the Mods forums about it, but I'm not too sure how to delete threads otherwise I would delete this one. D:

RP2 isn't updated to 1.6.4 get rid of it.

try ProjectRed its a RP2 replacement
