Mass-effect – How to “activate Alliance network” to play multiplayer in the demo

mass-effect-3

When I try to play multiplayer in the ME3 demo, I get this message:

Error

You do not yet have access to the online features of the Mass Effect 3 demo. Please try again later.

Back on the main screen there is this scrolling text:

Activate Alliance Network to Access Online Features

How do I do that? All I can find is speculation that it requires DLC or that you need to wait until the game is released, but obviously it's already been released.

Ah fudge, I post this and then I see some more scrollage:

Multiplayer demo is now closed. Single Player demo still active.

That's kind of lame. Does anyone know how long it was open for?

Edit: Found that too. February 17th to March 5th.
