Sims 4 update stuck on preparing

I bought the new expansion pack, for rent, a few days back and also the free romantic garden pack. My game needed updating and so I attempted to update but the app is not going past the preparing stage. I have tried re[airing the game but it again, does not go past 2% with me waiting hours and no change. I've restarted my computer, ensured nothing else is downloading etc on my gaming laptop (plenty of space on my disk) and have had no issues playing other games not from the EA app. I've opened the app as administrator and that also does nothing to help. I recall this issue happening before when I bought a new pack and I had to move files about but I don't remember how to do that!
