Spell Check doesn't work no matter what I do!

I remember when I brought Scrivener about a year ago it use to spell check just fine. But one day the red and greens lines highlighting errors just disappeared from under the words. Now weather or not I have spell check ticked in the options menu, it just never works whatsoever!

Please someone, is there anything I can do to fix this!? I’m seriously considering buying a new software at this point!

Hi I posted the same issue at the end of november and nobody found a solution. I’ve given up…
