Hello, Running splitter, now, this is the error I get : Exception in thread "main" java.lang.NoClassDefFoundError: crosby/binary/file/BlockReaderAdapter Caused by: java.lang.ClassNotFoundException: crosby.binary.file.BlockReaderAdapter at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) Could not find the main class: uk.me.parabola.splitter.Main. Program will exit. Last time I ran it (02/21) with the same parameters, it worked like a charm. Francois --
