OK, here is a .package version of the younger Gen 4 Samples: http://illation.net/Sims3/Uploads/Samples3-4-5.package
This is Zahra and Fabian as Elders, Charles and Veronica as Adults, Ada as YA, and the triplets as children.
Also, I pulled the package out DragonWife’s simself household. There was a pattern in the Sims3Pack along with the household, and it’s possible that’s causing problems with installing it. I don’t know if anyone else had trouble. At any rate, it’s here: http://illation.net/Sims3/Uploads/DragonWife.package
Both of these are files that you drop directly into the Documents/Electronic Arts/The Sims 3/Library folder rather than using the launcher.
