Hi,

I know that this post was created 1.5 years ago, but I was also having this issue too. This part is the issue:

[19:43:08] [main/FATAL] [FML]: There appear to be jars extracted into the mods directory. This is VERY BAD and will almost NEVER WORK WELL
[19:43:08] [main/FATAL] [FML]: You should place original jars only in the mods directory. NEVER extract them to the mods directory.
[19:43:08] [main/FATAL] [FML]: The directories below appear to be extracted jar files. Fix this before you continue.
[19:43:08] [main/FATAL] [FML]: Directory OptiFine_1.8.4_HD_U_D4 contains [MANIFEST.MF]
[19:43:08] [main/FATAL] [FML]: Directory Pixelmon-1.7.10-3.2-Beta contains [MANIFEST.MF]

Thanks!
