well i have downloaded content like cars and decorations from the thesims2.com website & it is now in my game. i have recently downloaded more stuff & it is save on my computer, but when i go to the content manager program the items do not show up.

things already on the content manager com up as something.package but downloads that do not come up are named something.SIMS2PACK
how can i get items like something.SIMS2PACK to come up as something.package so it will appear on the content manager???
