Greek spellcheck?

How can I add Greek spellcheck? (LibreOffice 4.1.1, Windows). I especially care having Greek spellcheck with the Writer.
Any tip would be really helpful. Thanks a lot in advance!

note1: I downloaded el_gr_v110.oxt 1.1, and appears in the Extension Manager. But still, no greek spellcheck when typing Greek.

note2: Clicking on “get more extensions online…”, takes me to this page which doesn’t have any greek dictionary extension.

Hey, problem fixed! (Don’t know how; maybe because of shutting down and starting again? Anyway, today spellcheck was working, at least with the Writer, which is what I mostly care). Please nobody bother, and sorry for any inconvenience. Cheers
