In the details of your error your mods are listed as

CrossbowMod2{a0.1.6} [Crossbow Mod 2] (Crossbow-Mod-2-1.6.4-a0.1.6.33.jar) Unloaded
GalacticraftCore{2.0.14} [Galacticraft Core] (Galacticraft-1.6.4-2.0.14.1084.jar) Unloaded
more{1.0} [more] (M-Ore 1.7.2 3.0Pre.jar) Unloaded
musiccraft{2.9.2} [MusicCraft] (musiccraft-2.9.2.jar) Unloaded
Scenter{1.7.2-3.1.0} [Scenter] (scenter-1.7.2-3.1.0.jar) Unloaded

The problem is clearly that you are trying to run mods that are not for 1.7.10 with 1.7.10.

  • CrossbowMod2 a0.1.6 is for Minecraft 1.6.4. Unfortunately, there is no version for 1.7.XX, let alone 1.7.10, so you will not be able to use it in 1.7.10 at all.
  • GalactiCraft Core 2.0.14 is for 1.6.4. You can try the beta-version for 1.7.10 instead.
  • M-Ore 3.0Pre is for 1.7.2. There's a version for 1.7.10 available though.
  • Musicraft I have no idea which version your mod-version (2.9.2) is for, but you can get Version 2.9.4 for use with MC 1.7.10
  • Scenter 3.1.0 is for 1.7.2. You can get Version 3.2.0 for use with MC 1.7.10

Remove the mods from the folder, download the correct versions (where possible) and try again (without CrossbowMod2)
