Just a quick update :
For all you guys that faced installation problems, everything is fixed now. I deploy my software with java web start and it's much more simple:
Whether you're on windows, linux, macosX, etc..., there's only on simple link to clic on. Go to the download page :

and select the java web start install. You'll have to say "yes" a couple times, but that's it.
Another great advantage: from now on, every time you'll launch the replayer, if there's any update on the server, it will automatically update itself.
