ok first i can play the god of war collection on my ps3 but i cant get the trophies. Now god of war 3 wont play becuase its unable to sync trophies or something, can anyone help me

Fix the date and time setting on your PS3.

You're going to have to go into a little more details.

1. Are you connected to the PSN first of all (actually make sure you are)?
2. What do you mean you cannot get trophies?  Please elaborate.
3. What is the exact error you're getting when you start God of War 3?

I'm guessing it's something to do with your date and time which should auto adjust if you connect to the PSN.

registration of the trophy information could not be completed the game will quit.

Yes i am signed in and i mean in the collection i cannot get any trophies and gow 3 will not play :(
