If you need to redo your code for redemption

[Ruthven78]

If you got the "invalid code error", WotC put in a fix so you should be able to resubmit.

In the steam client, go to the games section of your library, right click on MTG and click on "manage game account".


also to note, if you want to verify your expansion is installed, do the same as above but click on "view downloadable content"

If you see anything in the box the expansion should be installed. Mine shows "magic the gathering: duels of the planeswalker expansion..."
