Problem Downloading Sims 4 Packs.

Hello, i'm at my ends meet with this honestly. I've never had problems with sims 4 running, or downloading it in the first place. But I was trying to download some of the extra packs and kits, as I am working on a legacy challenge. The image below shows what it popping up. Not to mention, the add-ons are showing up as costing 666.00zlo. I don't know what to do.
