So I have been playing the Sims 3 64-bit since it came out and for some reason, the icons at the bottom left corner of the launcher won't highlight the expansion packs and the stuff packs I own. I can still play them and what not but they're not being highlighted.
I own:
EXPANSION PACKS
The Sims 3
Late Night
Ambitions
Generations
Pets
University Life
Seasons
STUFF PACKS
High-End Loft Stuff
Master Suite Stuff
Outdoor Living Stuff
Town life Stuff
