I paid for an upgrade on PS Express a while back . When recently I tried to use this app for editing there was a problem with loading up. Now that it loads up okay my upgrade isn't available to me anymore unless I purchase it again? This cannot be right..
Please check if you have added the same itunes account in settings with which you made the purchases.
