Forge 1.8 Crashes on Start

[FrenchFoxGaming]

Every time I try to use Forge 1.8 it crashes, and I have no idea how to read crash logs. I have only 1 mod in there so it is most likely the problem, but I don't know exactly what is wrong.

 

Crash Log:

Please post the latest client log file from %USERPROFILE%\AppData\Roaming\.minecraft\logs (provided you have not changed the minecraft directory for your forge installation). Please use the spolier tags (the button of the little eyeball) so that it does not take up page upon page.

 

*edit: I've also seen it said, if you really need to use a 1.8 version, to use 1.8.9 as it is more stable than 1.8.

I figured out the problem on my own. I apparently am just blind and didn't realize that when I had recently installed a modpack all of the mods were in there, and it was for a different version. Thanks for letting me know about the spoilers though
