So quite a while ago I bought the cats and dogs expansion pack and downloaded it to my computer. I played with it and it worked out for a while. Then I stopped playing sims 4 for a while. I recently got a new computer and wanted to redownload all of my packs back onto my new computer. I downloaded sims 4 and my other stuff packs but when it came to redownloading the expansion pack, it said the code was invalid. I tried to look up online what to do and a lot of people were saying that you can only use the product code once which I think is unfair.
Is is there another way I can get my expansion pack back or do I have to buy it again?
