My Custom Modpack Won't Extract Files

[Th3l0stSpart4n]

My custom modpack works fine in tests with a client side version of forge and I have ensured to properly prepare the bin folder. However, when installing it gives the error shown in this screenshot.

Please help me, as I cannot seem to puzzle this one out. A link to the pack can be found here.

• It is generally considered bad form to distribute the options.txt file in a pack because it will overwrite all client settings/options every time the pack is updated.
• CoFHLib is intended for use only by mod developers and does not belong in a client modpack.

That being said, the pack installs and launches successfully on both of my test systems.
