http://www.xmoonproductions.com/faq/#2_0"What about the 30 day download limit?
Of course you can still keep playing the game after 30 days.
Any future updates that are critical you can always download, also after 30 days. So don't be afraid that you cannot download bug fixes or patches.
When a new story is released we might re-price XStoryPlayer. In this case you only have to pay for the extra story. If the price remains the same for XStoryPlayer you can also download it without extra costs.
We try to keep the price low and fair, but also want to keep making new stories, so that's why we have the 30 day download limit."
That's what the FAQ page says. This just means you get what you bought, not whats coming. You can download that version as many times as you need to within 30 days of purchasing it. Lets say your computer explodes and you need to download it again after that time limit and can prove you own the email that made the purchase just ask here on the forum and Xpadmin will help you out in re-obtaining your copy. They're very good with customer support at xmoon. Hope that clears that up for you.
