launch4j error corrected

in case anybody run into the same problem, here is the solution:

delete or rename the existing arduino data folder, and restart arduino. then it works, and now you can just reuse the old sketchs and save in a new arduino folder.

in my case, the folder is under user/my documents/ arduino.

  16. Very great post. I just stumbled upon your weblog and wanted
    to say that I have really loved browsing your weblog posts.
    After all I’ll be subscribing on your feed and I’m hoping you write again soon!

  17. If you goto your My Documents folder and rename the Arduino folder (I use XArduinoX) and re-run the IDE it should work.
