Ok so I remembered that I downloaded a small java software a few days ago.
Back then I noticed that it changed/replaced some java files so I uninstall/reinstall java and it worked
Both FileBot and the software are working great now so everything's good !!
Thanks for the help and congratulations ...

I'm on windows 10, I installed it via the "FileBot_4.9.1_x64.msi" from your website.
I've tried lunching it via "filebot.exe" (C:/programmes/FileBot) via "filebot (console)" and via the CMD, same outcome.
When I lunch it via "Filebot (console)" the console is completely empty.

The App used to work very well but since a week ago, the app doesn't open.
I mean it opens but I cant see it and when I put my mouse on the icon (on the task bar) it's white.

I can't close the app (even with task manager) and when i click on it nothing happens ...
