You have an older version or a Labymod or a dependency plugin has changed it's class path.
net.labymod.vanillaforge.LabyModTweaker ? Changed it?

Did you also recently update a plugin/mod/spigot etc?
There is a way to fix this without the source or any java knowledge but it
is still quite complex to do.



Sourceforge. Class Editor.

Unzip labymod and LabyModTweaker jars into seperate folders.

In LabyModTweaker go to net\labymod\vanillaforge\LabyModTweaker
It's trying to find a class file in LabyMod that has either changed names or moved to
another folder. In LabyMod folder open up the class files and change the name/path as
it is now in LabyModTweaker.
(You can also scan the source if you have it with a search all files in folder Notepad++ for
easier finding the net.labymod.vanillaforge.LabyModTweaker changes. Update and save.
copy LabyModTweaker.jar and wipe it's contents, Drag the edited files over. Startup, check console.

Works? Congrats. You just fixed a broken addon/plugin without any java knowledge. GJ You. Boss!
You can also try using older versions of LabyModTweaker + LabyMod see if that removes the
no class found error. Wish you luck.

I just downloaded the newest installer, from Labymod's site- and it worked.

Thank you so much for the help! :)
