I just got a playstation vita today and tried to purchase a game online when I got this error message. It said that the network may be down although the main site says that its still up. It also said to check my region. I've looked all through the site and can't find where to go.
Any help would be greatly appreciated
This error has been occuring to the majority of people when they updated their PS Vita to version 2.0. Their seems to be a bug of some sort in the update, but I can suggest that you buy your game from the PS3 Store then transfer it to the PS Vita. Hope it helps.
