An, I went to the trunk\interfaces\src\main\java\org\dllearner directory and ran the following command: svn info confparser Output: Path: confparser URL: https://dl-learner.svn.sourceforge.net/svnroot/dl-learner/trunk/interfaces/ src/main/java/org/dllearner/confparser Repository Root: https://dl-learner.svn.sourceforge.net/svnroot/dl-learner Repository UUID: af9c125c-f337-0410-9a96-b85bd07cbc14 Revision: 3522 Node Kind: directory Schedule: normal Last Changed Author: jenslehmann Last Changed Rev: 2322 Last Changed Date: 2010-09-21 06:05:42 -0600 (Tue, 21 Sep 2010) So, it's currently at Project Version 3522, but has not been changed since version 2322. Running that config file (trains.conf) with the CLI (CLI.java) works well - but the StartGUI class was not updated to use the new configuration file with the current beta release. We focused most of our time on the command line and we are planning on writing a new GUI in the future. So as of now, the GUI in SVN on the trunk branch can not be used.
