Error with my license centreon

Hi everyone, I have link a multiple time this IT 100 I think because I have move and copy my centreon platform to different ESX so I think the licence is still there but its bugged, It is possible to remove the licence completly whithout the web interface ? like removing the file of licence of something like that ? then add another licence ? because the web interface seem bugged.

But I still think I have the licence because a can use Auto Discovery and we can the licence expires 9999-12-30
