My modpack won't run, please help

[SkyFl4m3]

Hi,

 

I have tried to make my own custom modpack, and when I launch it from the technic launcher the progress bar moves along, technic launcher dissapears and then re-appears after about 10 seconds, having done nothing.

 

Most of the log is fine, apart from this part at the end:

 

2014-08-21 08:00:15 [sEVERE] [ForgeModLoader] There is a binary discrepency between the expected input forgified class net.minecraft.block.Block (aqz) and the actual class. Checksum on disk is 1006975e, in patch 138a6550. Things are probably about to go very wrong. Did you put something into the jar file?
2014-08-21 08:00:15 [sEVERE] [ForgeModLoader] 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.
 

 

I am running 64 bit windows and java, and this is the modpack folder link:

Any help would be greatly appreciated.

Also, I have no files in the config folder as I dont know anything about that. Does that matter?

• The error you posted often occurs when your platform pack settings have the MC version set to one thing but the modpack.jar is a different version (i.e. settings are set to 1.7.2 but modpack.jar is Forge 1.6.4). This is why you should provide a link to your platform page or API URL when requesting assistance.
• Forge/MC 1.6+ (your pack is 1.6.4) does not use a coremods folder in any way. All mods belong in or below the mods folder.
• You have the Mekanism MDK (development kit). This does not belong in a client pack and should be removed.
• The MMMPS recipe files belong in configmachinemuserecipes not mods.
• Some of your mods have odd names (i.e. Waila. Don't rename the files which are downloaded from authors. Only get mods directly from the author's preferred distribution channels.
• You have the Forge universal binary JAR in your mods folder. This should be removed.
• You are missing your config files. This is always bad. Read through my guide on using the BareBonesPack to build a modpack for additional details on where config files come from and how to assemble your pack.
