The Sims 3 Lunar Lakes issues

Puzzleaddict, thanks for your quick reply!  I saw the date on your tag, I did not think, I would be hearing from you, so I greatly appreciate it you taking the time to reply.!..   Once I could not get Luna Lakes to play; I deleted other world save in sims 3, them I uninstall sims 3!   After that I clear cache, per Origin inst.   I proceeded to re-install sims 3 and download Lunar Lakes but I am still having the same problem.  I install it via the store, go to game download, then I install it from launched game, it let me now that Luna Lakes has been installed and to play I need to go to the main menu but its not there!!  The only thing I could think is, that I am missing a step?  Or Main menu is not where all of the other world that I had purchase are?  I will keep on trying. Since this happened twice before with two other down load! Once again thanks for helping !
