Thanks Aoktar !
I hadn't think about pref folder :p
So I deleted the entire folder using Edit / Preferences / Open Preferences Folder and it worked, the only problem is my plugins preferences are deleted. Maybe you could think about fix this little issue in a future update ?
Thanks for your support

Done !

Gosh sorry, first time I put images on a forum XD
Can you see it now ?
