This is an unfair policy. It isn't fair for those people that legitimately paid for the product and had the misfortune with their computer crashing. Its just isn't right to make them pay again. Aren't they getting enough money from people already? I know they're doing this to make it difficult for people to share their account with others that did not pay for their service. But they're going a bit overboard. It's not like you're getting top notch best of the crop service here. Their animated solutions suck beyond belief! It's true they're the "best" out there, but that doesn't give them the right to abuse their service like this.
Their tests haven't changed or have been updated. You may want to use your money and get new tests from like topscore or other DAT preps out there.
