If anyone, besides me, has this card, you should have already received notice that Kroger and USB are parting ways … and USB will be issuing a different card to replace it in your wallet.
I haven't received that new card, but when I tried to download onto the prior card, I got a "card not identified" (or some similar wording) error this morning.
I went to USB's website and saw the card was till there … but with a different card number.
SO, in Q, I deactivated the card from downloads and reactivated it (being SURE to "Link to Existing account") and was able to download from the new card account without issue.
Something similar to this process (perhaps the same) would apply to QMac also.
