Ok, I just bought splinter cell pandora tomorrow for my ps2. I have the internet on my playstation and it works on all my other games. But however, when I try to play multiplayer online, I go onto my account then I create an account for multiplayer. I log onto it and it says authenticating name and password but then it says unknown error.

What is going on and how can I fix it?

Try Chaos Theory. No more online for Pandora Tomorrow. Except XBox live I guess.
