Sims 4 won't install after Gametime

Hi, I understand this may be a little late and you have hopefully overcome this problem yourself but I had exactly this issue. I uninstalled the game and origin at least 4 times with no further progress past the 'Gametime has run out view special offer' basically wanting you to buy another copy!

I then found, within Origin on the top left corner of the window 'Redeem Product Code' The game was already installed from disc and still displayed Origin Game Time within the title of The Sims 4.

Once I entered the code including the '-'s between is changed to The Sims 4 and updated, and now it Works!!
