Re: "There's a problem with your download"/"Something went wrong" EA app Error - '24

I bought 3 days ago 2 kits + 1 pack as well as preordered the new pack. When I try to download the 2 kits or the pack, it loads an error saying ; "There was a problem with your download. - There was a problem with your download, please wait a few minutes and try again"
I tried, uninstalling the game, tried cleaning the EA cache, tried reparing the game (though as I play through Steam, it was more checking if there was any corrupt files), nothing works...
