Cannot Download Maker Packs from Marketplace

Hey!

I recently bought some Maker Packs from the Marketplace, but when I try to download them, it simply does not. The downloading bar appears at 0%, and after a few moments, it says "Download Failed". When I go to the Download Manager, it states "Couldn't Complete Download". It also does not allow me to delete this message.

The packs in question are "Reader's Nook", by ValiaSims, and "Rustic Nest", by KKBsMM.

I've tried to clear the cache, repair the game, uninstall and reinstall the game - but nothing worked.

What can I do?
