Hi. This is my first time attempting to mod Minecraft without using a separate modpack launcher. I installed the latest version of forge and managed to get it running, however, when I came back to the game later, after adding some mods into the mods folder, I attempted to launch forge again and it ran into an error and failed to launch. This is the latest log report of the error:

I've removed the forge launcher from the libraries' net folder, as well as the mods from the mods folder and reloaded the forge launcher several times, even changing to the site's recommended download of forge to see if that affected the outcome. I would REALLY appreciate any help you might have to help me find out what is happening and how I can fix it. I'm sorry if I'm leaving out anything necessary. Let me know if I need to include something else.  :P

Thank you for pointing out the problem. Forge is launching properly now it looks like but you could have simply told me that the chicken core version was what was causing the problem instead of going "...really?" like I'm an idiot. I'm not used to coding or modding and I said that. I still appreciate the help though

I would of been political and held your hand nicely but thats now how the world works.

This way you actually do a little bit of thinking for yourself and get the last little bit of the solution yourself.

AND you see how the solution was derived from the log files.

Theoretically you'll keep this knowledge and use it next time you have issues to try and solve it yourself.
