So i want to start a Voltz server for me and my friends and i put all the folders in all the right places and then when i launch the server the console comes up with this: 12.01 05:40:24 [Multicraft] Server stopped 12.01 05:40:24 [Multicraft] Looks like a crash, check the server console. Return value: 1 12.01 05:40:24 [Multicraft] Server shut down 12.01 05:40:24 [server] INFO ... 13 more 12.01 05:40:24 [server] INFO at java.lang.ClassLoader.loadClass(Unknown Source) 12.01 05:40:24 [server] INFO at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) 12.01 05:40:24 [server] INFO at java.lang.ClassLoader.loadClass(Unknown Source) 12.01 05:40:24 [server] INFO at java.net.URLClassLoader.findClass(Unknown Source) 12.01 05:40:24 [server] INFO at java.security.AccessController.doPrivileged(Native Method) 12.01 05:40:24 [server] INFO at java.net.URLClassLoader$1.run(Unknown Source) 12.01 05:40:24 [server] INFO at java.net.URLClassLoader$1.run(Unknown Source) 12.01 05:40:24 [server] INFO Caused by: java.lang.ClassNotFoundException: ab 12.01 05:40:24 [server] INFO at sun.launcher.LauncherHelper.checkAndLoadMain(Unknown Source) 12.01 05:40:24 [server] INFO at java.lang.ClassLoader.loadClass(Unknown Source) 12.01 05:40:24 [server] INFO at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) 12.01 05:40:24 [server] INFO at java.lang.ClassLoader.loadClass(Unknown Source) 12.01 05:40:24 [server] INFO at java.net.URLClassLoader.findClass(Unknown Source) 12.01 05:40:24 [server] INFO at java.security.AccessController.doPrivileged(Native Method) 12.01 05:40:24 [server] INFO at java.net.URLClassLoader$1.run(Unknown Source) 12.01 05:40:24 [server] INFO at java.net.URLClassLoader$1.run(Unknown Source) 12.01 05:40:24 [server] INFO at java.net.URLClassLoader.access$100(Unknown Source) 12.01 05:40:24 [server] INFO at java.net.URLClassLoader.defineClass(Unknown Source) 12.01 05:40:24 [server] INFO at java.security.SecureClassLoader.defineClass(Unknown Source) 12.01 05:40:24 [server] INFO at java.lang.ClassLoader.defineClass(Unknown Source) 12.01 05:40:24 [server] INFO at java.lang.ClassLoader.defineClass1(Native Method) 12.01 05:40:24 [server] INFO Exception in thread "main" java.lang.NoClassDefFoundError: ab 12.01 05:40:24 [Multicraft] Loaded config for "Default" 12.01 05:40:24 [Multicraft] Starting server!
