Minecraft Forums

I've been playing Minecraft for a while, but never with mods. I've downloaded a few, but then soon realized I couldn't use them all together. So I tried getting forge/FML. They don't seem to work. It creates a profile with the forge/fml .jar file, but as soon as it exectutes it crashes. Here is the FML crash report:

Sorry if this isn't proper forum etiquette, I don't really talk with the community often, but I'd like to use these mods and I can't seem to find an answer.

Further investigation shows me that Forge/FML work when there are no mods in the mod folder. However, when I put optifine/shaders .jar in the mod folder it goes crazy and crashes

Self-Bumping for more views if this is how it works.
