There's something wrong with your mods folder:

 

First, some mod archives are corrupt:

[11:38:47] [main/ERROR] [FML/]: Unable to read the jar file ThermalExpansion-[1.7.10]4.0.0B5-13.jar - ignoring
java.util.zip.ZipException: error in opening zip file

[11:38:47] [main/ERROR] [FML/]: Unable to read the jar file ThermalFoundation-[1.7.10]1.0.0B3-8.jar - ignoring
java.util.zip.ZipException: error in opening zip file

[11:38:47] [main/ERROR] [FML/]: Unable to read the jar file twilightforest-1.7.2-2.2.3.jar - ignoring
java.util.zip.ZipException: error in opening zip file

 

Then, you have a lot of duplicates:

 

[11:39:01] [Client thread/ERROR] [FML/]: Found a duplicate mod Growthcraft at [C:\Users\Huw\AppData\Roaming\.minecraft\mods\growthcraft-core-1.7.10-2.1.0a.jar, C:\Users\Huw\AppData\Roaming\.minecraft\mods\extrautilities-1.1.0i.jar]
[11:39:01] [Client thread/ERROR] [FML/]: Found a duplicate mod Growthcraft|Bees at [C:\Users\Huw\AppData\Roaming\.minecraft\mods\CoFHCore-[1.7.10]3.0.0B6-32.jar, C:\Users\Huw\AppData\Roaming\.minecraft\mods\growthcraft-bees-1.7.10-2.1.0.jar]
[11:39:01] [Client thread/ERROR] [FML/]: Found a duplicate mod MekanismGenerators at [C:\Users\Huw\AppData\Roaming\.minecraft\mods\immibis-core-59.0.1.jar, C:\Users\Huw\AppData\Roaming\.minecraft\mods\MekanismGenerators-1.7.10-7.1.1.127.jar]
[11:39:01] [Client thread/ERROR] [FML/]: Found a duplicate mod MekanismTools at [C:\Users\Huw\AppData\Roaming\.minecraft\mods\InventoryTweaks-1.58-147.jar, C:\Users\Huw\AppData\Roaming\.minecraft\mods\MekanismTools-1.7.10-7.1.1.127.jar]
[11:39:01] [Client thread/ERROR] [FML/]: Found a duplicate mod Waila at [C:\Users\Huw\AppData\Roaming\.minecraft\mods\OpenBlocks-1.7.10-1.3-snapshot-433.jar, C:\Users\Huw\AppData\Roaming\.minecraft\mods\Waila-1.5.8a_1.7.10.jar]
[11:39:01] [Client thread/ERROR] [FML/]: Found a duplicate mod witchery at [C:\Users\Huw\AppData\Roaming\.minecraft\mods\witchery-1.7.10-0.22.0.jar, C:\Users\Huw\AppData\Roaming\.minecraft\mods\OpenModsLib-1.7.10-0.6-snapshot-224.jar]

 

 

I suggest redownload the corrupt mods and delete the duplicates.

if you take a closer look at what the duplicate is saying

 

Found a duplicate mod Growthcraft at [C:\Users\Huw\AppData\Roaming\.minecraft\mods\growthcraft-core-1.7.10-2.1.0a.jar, C:\Users\Huw\AppData\Roaming\.minecraft\mods\extrautilities-1.1.0i.jar]

 

 

from my understanding those two path's are the duplicates, so growthcraft is a duplicate of extra utils?

 

unless i'm reading this wrongly (entirely possible, i'm new at this)

 

i'm pretty sure there's only one of each mod in the folder, i've checked twice and moved each file over one by one

Where are you downloading these mods from?

FML won't say they are duplicates, unless they are duplicates.

 

directly from the creators sites/minecraft forums

I doubt that consdering you're downloading the same mod under different file names.

THere isnt much we can do about that, you have duplicates.

why would i lie? i've come here looking for help

 

this isn't the first pack i've compiled, this is the first time i've run into any problem

 

some of the files that are registering as duplicates have been used on my old server because i didnt need to update them

they didnt register as duplicates then

something is going wrong and im asking for some help

With what we have there is nothing I can do for you.

YOu have duplicates simple as that.

For further help you are required to provide your mod pack and a list fo EXACTLY where you downloaded every mod.
