You're not sorry and you couldn't have looked very hard. Where did you find these store items? Look there for your answer.
When I "install" the content, it always shows me a success message, but once I play the game, the items aren't there. I don't know if that helps my sorry case at all. And I am sorry for the n00b question, as you "elitists" are too busy for less intelligent people who need genuine help. I did state that I looked for an answer, and I have been looking for a while. But hey, if I appear too stupid for you to help, then that's fine by me. I don't get why everyone has to be so rude when there are stupid people in need of help. I apologise for wasting your time. I didn't realise I was such a mindless idiot for asking for help when I needed it. :\
