Mine worked fine, but I got to it early and I triple checked to make sure I was applying it correctly to the game I wanted. The coupon does have an advantage over, say, a sale weekend in that you can choose what game or app you want to apply it to. But the fact that this is not a weekly phenomenon like the weekend deals and giving very little notice about when it was going to be released was probably its greatest downfall. For those who are not constantly checking the website, email, or simply not available during the time offered, it's basically moot. But on the plus side, Stardock is good about listening to their customers and changing their behaviors based on lessons learned. I wouldnt be surprised if a second set of coupons would be sent out to "make up" for these issues with more notice in the near future. I do hope they give more of a time frame of say a week to use them. I guess all we can do is keep watching the site and checking our email while hoping for the best.
