Hello, sorry for my bad english I'm French.

I'm using forge and a custom Launcher for my server (https://www.launchmycraft.fr), and my launcher just crash before the game Launch.

 

**THAT NOT A CRACKED LAUNCHER, THAT A CUSTOM LAUNCHER WITH AUTH ! I USE THIS LAUNCHER FOR MY PRIVATE SERVER**

 

I'm using forge 1.8.9-11.15.1.1756, and with the official Launcher that working well...

 

Here is the logs :

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/logging/log4j/Level

Thanks in advance.

Cordially.

You're missing a required library (log4j), which is almost certainly an issue with your launcher.

"Pay us and we'll remove the need for credentials on your launcher!" Really... really not a cracked launcher!?!?
