i cant access the different worlds i have downloaded

ive just downloaded the sims on my pc again after having given up on it in the past, and since i downloaded all the dlcs i have on the game they were first showing up were inacessible, and saying i needed to restart the ea app. that didnt work, so i searched it up on this forum and followed a tutorial. so then i deleted the dlc downloads from the steam download and downloaded them again from the ea app. when i finished downloading them all and started the game up again they werent showing up at all. help please i just want to play the game i hate ea
