I just made the same mistake via Amazon. Ordered Federal only. I realized the mistake after I downloaded it but before I used the activation key. I call Amazon Customer Support at 1-888-280-4331. Only had to wait a few minutes, and then a few minutes later they said they would issue a refund, even though at the outset they stated that their policy was software downloads are non-refundable. So, kudos to Amazon for making it right.
