Can someone please explain to me how to turn antialiasing on?

Okay, maybe I'm a complete moron, but I've been messing with this since I got the game and I can't turn on AA. The option always remains greyed out in the video options menu, no matter what other settings or resolutions I try. I even tried a fix someone posted elsewhere involving changing the AllowLeaderAA setting in the GraphicsSettingsDX11 file (or tried to--mine is called DX9, even though I don't play it in that mode, but I tweaked the setting anyway) but it didn't change anything. Can someone please help me figure out how to get this working? Games tend to look a bit crappy without AA, and my system is more than capable of handling it. Here's a screenshot of my video options:

Also let the new little patch download today. Didn't change anything.

Vista does not support DX11, as far as i know, so you're playing DX9 (i guess, not100% sure).
Please look at this post.

Gorgeous! Looks like a whole new game, graphically. This will do until Vista gets DX11 support worked out, if ever. Thanks a ton.

Vista does support DX10, and probably will never support DX11, Since 7 is now available.
