I've been trying to install Minecraft Forge 9.11.1.953 so I can start modding, but after a certain period of time, it just stops working without displaying an error message or anything. I don't think I'm being impatient because I've tried giving it a whole hour. I've also tried installing each of the other 1.6.4 forge versions, but the same thing happens. Does anyone know how to fix this? If so, how?

Logs? (forge/mcp/logs/mcp.log)

This is as far as it got this time, sometimes a bit less, sometimes a bit more:
