Redeemed codes for both hot wheels and blizzard, but theyre not working.

Hello i have redeemed both hot wheels and BM awhile ago on my old computer.
I reinstalled the game on my new computer but the hot wheels and bm modes are not working.
And its saying to purchase them again.
I have achievements and trophies from both modes so its clear that i have had the expansions before?
why is it telling me to repurchase them?
