hey i've bought the game before, deleted it today by accident and now it's saying that i have to pay again?
I'm not sure of the format on mobile, but on PC there should be an arrow pointing down near your name in the upper banner. If you click that a drop down menu will appear. Select 'My Purchases' on the menu. That will open a new page with a list of all the games you've bought and have a button that says Download under each game. Clicking the download button will take you right back to the original download page where you can get it again :].
