Whenever I run the launch.bat file for my server I keep getting this:

Everything is up to date as far as I'm aware, all mods are the latest build as well as the Tekkit server itself, it stated before that it is likely being caused by a corrupt .jar in the mods folder but it no longer says this so I'm a little stumped.
