So I tried running my client to look at the item in episode one. The first run, but I keep getting this error: Error: Could not find or load main class net.minecraft.launchwrapper.Launch

This is what I have

It should be package.CoreCraft

Quote from nathan5541

actually no. do you know where i can get the mcp folder with the forge folder and stuff inside of it already? i have all the programs installed. that folder is probably the problem.

Quote from Animefan8888

The item id 2000 and 2001 is used already and is overriding the item that has it

Quote from nathan5541

But it was working just fine before i added the block. Plus, when I log into vanilla minecraft and type
/give nathan5541 2000
it says that there is no item with that id number.
