Indeed... I've seen it now, lots of people are having the exact same issues (in my case, like others, it's the "time out" connection issue). The thing is that I've paid for the extra content, it's the Digital Deluxe Edition, I wanted it, and I did not want it only for useless bragging purposes since modders or pirates will make extra content available for free anyway, I simply paid for it to support BioWare and thank them for making the game, and obviously I want to play with that extra content even if in the end I'll end up not using a single of those extra items since they "suck" compared to the vanilla items just like it was in Dragon Age (for my own characters builds anyway), I want that extra content recognized and enabled from my very first game.
I've finally been able to access the "main menu" and adjusted the in-game settings, but I still haven't started a "new game", not until BioWare and/or EA fix their stupid Cerberus crap, which I've never been fervent about, we have enough of Steam as a layer to deal with before playing our games. I also had some problems with Dragon Age: Origins and the DLCs. It's getting frustrating, I don't have much patience for that kind of thing, but like many others I'll deal with it until it's fixed. I hope that I'll be able to play with the extra content I've paid for today, the very same day that the game has launched.
If in the end of the day BioWare and/or EA haven't fixed the time out issue then it will be the very first time in my entire video gaming history that I haven't been able to play a game with the content I paid for due to external (developers or publishers) issues the same day it was made available, it would really be a first, for me anyway.
