Greetings
I'm so curious! Can any one tell me why I have 2 DVD'S? I bought the the standard PC version, in the box are 2 DVD'S one marked Game Disc One the other Game Disc Two. When I installed the game it fully completed from Disc one and I am am now playing the game successfully

. I t never asked for a second disc during install. If now i put that second disc into the pc it refuses to do anything saying that it "Failed to authenticate disk please try again."

The second disc is inside a black cardboard EA wallet.
What is the second disk for?

I actually also had the same thing when I bought Mass Effect but never bothered to follow it up.
