custom modpack wont load mods

[tenorsaxman53]

hi everyone i am trying to create a mod pack but when i run the mod pack it just runs as if it was vanilla  if anyone could help that would be great! the link to my mod pack is here http://api.technicpack.net/modpack/mechanical-land    I deleted all the mods except for NEI and what was needed to run that to see if any mods were the issues but still nothing is working.

• Your pack contains too much stuff. It should contain only these folders: bin, config, mods
• The /bin/ folder should only contain the file modpack.jar. Your modpack.jar file is actually named "modpack.jar.jar". Google "windows explorer always show file extensions" to learn how to prevent this.
