I've been unable to access the PS Store for the past two or three weeks--ever since the most recent update. Every time I go on it says, "This service is under maintenance." I'm hoping that if I choose delete it will simply delete the update and I can reinstall it. There's no way to permanently delete the Playstation Store from a PS3, is there?
Good gameplay can easily salvage a bad story. Good story can never save bad gameplay. The best games, however, have both.
jokes aside, you deleting it deletes the updates for it. the icon will still be there and when you select it will reinstall the store and whatever update its on theoretically fixing your issue. so you're a pretty bright yoshi for coming to that solution. another thing you can try is getting your ps3 to safe mode and doing option 4 to rebuild database to fix the file pathes to the store.
