okay so i try to get on cod 5 today, and it says Unable to connect to Authentication Service (Error 34). And all my zombie maps are disabled, button layout, sensitivity is changed. I cant even go to the story, it says they are locked, except the first one, Does this mean i have to start over? Are my map packs disabled now? And now i try to sign into playstation network, and it says it undergoing maitnence. How long will this take? and will everything go back to normal that i described?

ok so i try to get online on cod5 on my ps3 and it wont work. like i can play one game. and once the game is over it will sit on a loading screen. so i have to turn it off. but when i play on cooperative mode, and play nazi zombies and things like that. it works fine. soo i dont understand it and need helpppp!!!
