Aperture 3 not sharing updated Previews with iLife/iWork

I have been experiencing an issue with Aperture 3 since updating to 3.4 (and still with the 3.4.2 update I installed on 11/4/2012).

Basically, iTunes, Settings (Desktop/Screensaver) and any iWork app (including Keynote from App store) when loading in the Aperture library doesn't load images I've been adding to Aperture over the last 3 months. It gets my photo stream, but nothing else that I've added since August (I've added hundreds of images, non-photo stream images, since then).

I've tried doing Aperture Library repair/rebuild.

I've tried deleting iPod Photo Cache.

I even tried re-installing iTunes 10.7

What else can I do? I installed Aperture before App Store was out, so it's not as if I can re-download Aperture from App Store and do a re-install.

Short of just removing Aperture, re-installing 3 from the original version I bought then doing all the upgrades, I don't know what else I can do. This is extremely frustrating as I can't get any new images on to my iPhone 5 or iPad 3 and my Desktop/Screensavers can't use my latest images, even from Smart Albums (like 5 star album, which I usually use for Wallpaper Rotation and Screen Saver on my Apple TV).

Would love some help. I was hoping Aperture 3.4.2 would fix this, but no. I thought iTunes 11 might hold hope, but since all other iLife/iWork apps are experiencing the same issue it seems that won't help either.

Configuration details:

MacBook Pro 17-inch (early 2010)

Mac OS X 10.8.2

Aperture 3.4.2 (library size approaching 200GB)
