Basically when I try to run my client (Modified MCP) it gives this crash log:
Preparing to launch minecraft client for Luna
Local file C:/Users\ME\AppData\Roaming\.minecraft\assets\indexes/1.8.json has wrong SHA-1 hash, expected but was e264980ad255aad2174cbe4d674c102474ae5202
Deleted Local file C:/Users\ME\AppData\Roaming\.minecraft\assets\indexes/1.8.json

Couldn't get hash for Luna jar from https://s3.amazonaws.com/Minecraft.Download/versions/Luna/Luna.jar.sha1: HTTP 403: Forbidden
Have local file C:/Users\ME\AppData\Roaming\.minecraft\versions\Luna/Luna.jar but don't know what size or hash it should be. Have to assume it's good.
Minecraft client Luna requires 18446744073689194157 bytes to download.
Version does not support log configuration, will assume one plaintext entry per line
Then it crashes.
