I did not want you to purchase the Online Map Pack. I don't want you to spend any money if it's not going to work.

You said you downloaded the Compatibility Packs, and yet you couldn't change that? Well, then it sounds like you purchased DLC for a region where the game is incompatible.

We can't help you any further. Go here http://gr.playstation.com/support/ and try to contact them for help (I can't understand Greek, so I can't help you out).
