[1.8] Can't launch my mod

[Jester]

I created a mod using MCP for 1.8 (mcp910) (i can't use forge, need be mcp910)

 

But, whenever I try launch the minecraft version (1.8 - Modded)

Minecraft cancel's the launch and install a new jar for 1.8

 

Someone know this?

 

I'm putting the "reobf" files at  "1.8 - Modded.jar"  it's that right?

Then why are you here?

These are the Forge forums, not the MCP forums.

Because don't exist a mcp forum. You are soo kind.

While that may be, you're still not going to get help here, as help here is offered for Forge, not Bukkit, not raw MCP, and not coremodding.
