[Current Issue] Sims 3 "serious error" when loading save | EA Forums - 8322938

For your packs, do you see them in the launcher's Expansions & Stuff Packs tab?  It sounds like you have a number of worlds to choose from when starting a new save, which means those worlds are installed and recognized, but I'm not sure whether you only see Sunset Valley and Store worlds or in fact all the worlds that come with your expansion packs.  Regardless, the "serious error" does not necessarily mean that the EPs or worlds are installed improperly, and in fact that's probably not the issue if you can't even start a new save in SV.
