P.P.S. I wouldn't be mad about any of this, if knew that buying the last update at a discount wouldn't get the next one release day. Just be clear on wether you're talking about the actual price paid or the "listed full price" of the product tier bought.

This site is not set up the way Steam is set up. If you bought something for $5, then you get it for $5. If I add a new version for $10, then you won't be able to get it, because. paid $5. Yes, it's weird. Is it fair? No. But there's nothing I can do. This is how this site works. The only solution I can offer you is to refund $5 and add $5 to buy the game for $10.
Steam works completely differently. There, if you bought a product - you get it forever. Why the developers of this site do not do so - the answer must be asked from them.
