Have you uploaded a save? You need to save a game on PS3/Vita then upload it to the cloud before you can download.
If you have a save currently on the cloud (you can only have one at a time), and you are still getting the error, then it is likely a PSN/Maintenence issue. If the problem persists for more than a couple of hours, you may need to contact Sony support.
