Here is a more extensive and up to date set of collections for decrapified stuff (162 166 169 173 total).  Some have been combined, such as:
Celebrations - 3 sets in 1
Halloween - 4 sets in 1
Happy Holidays - 4 sets in 1
Happy New Year - 2 sets in 1
Harvest Bounty and Fall Fruition together
Iams Pet Starter Kit and Iams Sofa together
Steampunk and Steampunk: The Return together

All collections have the store content icon.
Some "full sets" are left out since they don't have any new items from the separate sets.  Some "full sets" are included because they do have more items, namely fences.
A lot more collections have been added, like SimPoint Bonus Items, Dr. Pepper and T-Mobile promotions, free items, and world items.
All files are named appropriately.  Please note if you change anything about them, the file is recreated and the name will be lost.

I put the link to an earlier driver, not a newer one.  Did you try the one I linked to?
When you try to install it, it should tell you that you already have a newer driver installed, and ask if you still want to install the older one.  So just say yes.. I can only speak from my own experience, but it worked for me, and I now do have the expansion, also working.
Also, make sure to restart your computer after changing the drivers.

I don't have the expansion, but I was actually having this same problem with the base game.  I fixed it by going back to an older driver for my video card.  This one worked for me:

I hope it works as well for you!

Oh, thanks!  I don't know how I missed that. 

Since I don't think it's been posted yet.. I've made a package for Elder Male "The Red and White Veteran Knight"
Unfortunately, I can't buy from the store, so it's just a recolor of the mesh using the texture from the Adult outfit (Better than nothing in my opinion!)  It'll show up along with the other store outfits.  I didn't include the mesh in the package, so you will need one of the other outfits of this mesh.
