Weird ! display

From VuzeWiki

If you are getting weird display of that kind:

!formats.units.kb!
!Formats.units.perspec!
!MainWindow.menu.window!

you need to exit Vuze, look for MessagesBundle*.properties files in the Vuze program directory (in Windows systems it is usually C:\Program files\Vuze (or \Azureus)). If you find such files, delete them. Then launch Vuze again.
