So now to my Question. I had downloading the SERVER SVN with Eclispe, i had compile it (with no errors and co) then i want to start the L2J_Configurator but ill become the Message Error: Invalid or Corrupt JarFile. Ok, so i think now, I download the SVN again but now with tattoisene(damnd.. i cant write this s*** programm) and put the Project Manually into Eclispe and it goes perfectly. Now my Question.
Was this my Mistake or had my Eclispe a Problem with SVN?

And for Other that become the Error, Download the SVN manually and add manually the Project to Eclispe. Thats solve all Problems with "Invalid or Corrupt File."
