Sorry we don't support 1.7.10 (it's 4+ years old!) or any version under 1.10 on this forum anymore due to their age. We simply don't know how to help you anymore. You can go to the Minecraft Forum where I think that they still still support older versions, or update to a modern version of Minecraft (the latest version or the one before it) to receive support on this forum.
