Re: My Sims 3 Game says only available on Mac
@Destiny_Hope24 You should absolutely not need to buy the game again. Please make sure you don't have any filters enabled in your game library; you can open the filter settings in the upper right corner of your game library.
If that's not the issue, please contact EA customer support for help; it should be simple enough for a support rep to check your account and add back whatever is necessary.
