Hi there!
I'm trying to create a modded server for me and my friend and when I was about to log into the server to see if everything was working properly it doesn't allow me and displays the message "Fatallly Missing REgistry Entries"
I have tried looking for posts in the forum about this but haven't found a concrete question on why this happens and how to solve it.
In the posts I have seen, the people were asking what mods they were using and their server log so:

Log:
I have those exact same mods downloaded on my mods folder and I don't understand why this is happening.
I would really appreciate it if someone could help me 
Sorry if I made any grammar errors. English is not my first language.
Thank you for your attention.
