Installation problems….
If you are experiencing any problems with Distant Suns 3.2 after upgrading, particularly if it is unable to launch properly, this could be a corrupted download from the Appstore that can hit any app. Delete Distant Suns 3.2 from your device and try reinstalling directly from the Appstore and see if that takes care of things. And no, you will not have to purchase it again.
And if it still has problems, contact me and we’ll try and sort things out.
