Custom Modpack fails to launch

[korroth]

Hello, I'm trying to set up a modpack for my friends and I to play on. When I load it up on the vanilla (or ex-vanilla?) minecraft installation, it loads up fine and everything works as far as I can tell. So I uploaded it to Dropbox, linked it on Technic, and was able to install it. However, whenever I hit play it fails to start. It doesn't even load up a window.

Any ideas why? If there is an error log or something somewhere, please let me know and I will upload it.

Edit: Removed some mods/config files to see if lightening the load would work and updated the links.

Found this log, but I have no idea what .jar it is referring to:

[23:36:04] [main/DEBUG] [FML/]: Running coremod plugin for FMLCorePlugin \{net.minecraftforge.fml.relauncher.FMLCorePlugin\}
[23:36:04] [main/DEBUG] [FML/]: Running coremod plugin FMLCorePlugin
[23:36:05] [main/DEBUG] [FML/]: Injecting tracing printstreams for STDOUT/STDERR.
[23:36:05] [main/DEBUG] [FML/]: Read 1066 binary patches
[23:36:05] [main/DEBUG] [FML/]: Loading deobfuscation resource /deobfuscation_data-1.12.lzma with 36066 records
[23:36:05] [main/FATAL] [FML/]: There is a binary discrepancy between the expected input class b$1 (b$1) and the actual class. Checksum on disk is 52fe6ed7, in patch 44e36e75. Things are probably about to go very wrong. Did you put something into the jar file?
[23:36:05] [main/FATAL] [FML/]: The game is going to exit, because this is a critical error, and it is very improbable that the modded game will work, please obtain clean jar files.

The version of Forge you included is for Minecraft 1.12, not for 1.12.2. Make sure to download the right version.
