I get signed out of psn when loading minecraft playstation edition (ps3)?

When I load the game, I get to the logos before the menu and I get signed out. There's no error messages it just says signed out. My friend is on the game an I can play other games, this only happens with minecraft.
Game info: I have no dlc. It has parental control level 3.

I have restarted my ps3, reinstalled the game( as it is a download) and restarted my router.
Can anyone help?

I can. I had the exact same problem. When i was about to sign in, i pressed the 'forgot my password' button, and reset my password. I signed in with my new password, and it works as if i never had any problems with it. Hope this helps.
