That error message means that yEd was not downloaded completely. The demo consists of two java archives, yed.jar and vectorgraphics.jar, and the error message means that yEd was started without vectorgraphics.jar being available. Usually, this is a problem with the client that is trying to run yEd. What operating system and what Java version are trying to run yEd on?

Thank you for your information.  I am now running Java 7 u45, and the demo runs OK.  I may have had an incomplete install of the Java update when I had the error.  The install completed when I re-booted today and the demo runs.
