It's the same song on a different day. Much like how BioWare had some DLC issues when Dragon Age: Origins was released back in November, the developer is dealing with some of the same issues for the just released sci-fi RPG Mass Effect 2. Folks on the BioWare message board have complained about not being able to sign into the game's DLC-based Cerberus Network. BioWare's Chris Priestly has posted up word that, "We are actively pursuing a fix to this and will update everyone once it is fixed on the server-side."

Priestly also has some workarounds and advice for folks who have had other download issues particularly for folks who have the PC Collector's Edition of the game.
