I ran Ambitions without mods. Because my former graphics card blew up I turned fps on to check. I seldom saw more than 60 fps, which was different before Ambitions. Could it be that EA worked a limiter in with the newest patch?

I've donated a few Dollars and mentioned my nickname in the additional info box.

I had the same problem (NVidia 8600 GT). The newest driver version from NVidia crashes the game, as I learned from a quick research in Google. When I reinstalled the previous version, verything was O.K.

  Works fine for me, looks great, love it. Besides the plain shirts most of the clothes are O.K.

You could be right, I just took them out together, perhaps the Peggy hair is fine, but I realized I didn't use it anyway. I wonder if it is the replacement thing that causes the crashes... there's one new non-replacement long hair mesh from Peggy, I guess I give it a try.

I used the SAU hair and the replacement Peggy hair recently, but it seemed to me that they are causing crashs. Without them all worked fine. Now Peggy has a non-replacement hair - does that make a difference or should we trust more in HP's abilities?
