sims 4 seasons refuses to download

[wallysis2016]

I have a mac system, and when I typed in the product code it acknowledged the code but the game did not start downloading.  Now the code says it has been used already, but Sims 4 Seasons is still not in my game library and nothing is being downloaded either. please help!

Click the game in your Game library then Extra Content. You will find the expansion in the list of expansions you own.
