Sunlit Tides Just Won't Download (The Sims 3)
I have cleared the cache on both my browser and the launcher, does not work. I have repaired the game files and the EA App, does not work. I also put the game folder on my desktop, does not work. ...
@phinioxflare456 Try downloading Sunlit Tides from either your purchase history (Store > My Store Account > Purchase History) or the product page, whichever you have NOT been using. Here's the page for ST:
https://store.thesims3.com/sunlittides.html?categoryId=12642
If that doesn't help, can you try downloading over a different network, for example using your phone as a mobile hotspot?
Additionally, do you own the standard version of ST or the gold version, and if gold, can you download the standard version instead? The extra content from the gold version is just the Serenity Retreat venue and its accompanying items, and this can be installed separately.
