MD5 verification failed when installing source of forge.

I thought to learn modding for minecraft, so i downloaded "source" of 1.6.4 version of forge from this forum.

http://www.minecraftforge.net/forum/index.php/topic,14059.0.html

when i try to run the thing, this is what i get:

Something failed verifying minecraft files, see log for details.

Decompile Exception: 1

続行するには何かキーを押してください . . .

I have tried the following:

1, make the path of download contains only english charecters.

2, move jar folder in fml in to fml_data, delete fml and redo things.

3, use a VPN.

now it still wont work. my question being why this happens and how to fix it. does it have anything to do with my japanese system,, java 7, or is the resource on the internet corrupted or something.

i want to add that:

1, im using windows 7, 32 bit.

2, if all fails and i just need to download those files one by one, where should i put them?

Having the same issue here.

What I've tried so far:

1. Downloading all the .jars manually and adding them to "fml\mcp_data\jars" as per Lex's advice here http://www.minecraftforge.net/forum/index.php?topic=11898.0

Re-running the installer simply reports the jars as modified, deletes them and then fails when trying to re-download them.

2. Setting up MCP independent of Forge, which does successfully download the libraries. Again then adding them to "fml\mcp_data" but Forge still regards them as modified, same as before.

Is there anyway to stop Forge removing the libraries? As they definitely aren't modified.

Re-download the src distro, i've fixed it to reflect maven's and mojang's changes.

Or, you know, use the gradle which has had this fixed for a week.
