Hi, I have this in my sources.list: deb http://eric.lavar.de/comp/linux/debian/ unstable/ deb-src http://eric.lavar.de/comp/linux/debian/ unstable/ So I have installed freemind unstable. Here is my problem when I'am trying to start freemind this error message appears: Error loading class freemind.main.FreeMind: Bad major version number What can I do to start freemind without error's ? -- Best Regards, Mark
