You cannot do anything until they release the patch this week.
Do a search on here for it and you'll see it has been asked many times already. Read this.

This is known problem. It will be fixed in the next patch.

Sadly I will be well past that point which makes the DLC and my unavailable bonus content usless. As for playing through again, not anytime soon.

I know that feeling.
This is really starting to suck!
I even had Troll trouble downloaded and installed yet i got to chapter 1 and the notice on the board outside the inn says to go to official forums and register to get the Troll Trouble DLC.
Obviuosly i cannot do that since there are no official forums, and no re-registering or verifying the game fixes it.

The swordsman outfit download doesn't seem to be working, either. After an hour and a half I gave up.

It'd be nice if it gave something like a progress bar, or something.

Swordsmans outfit is the bonus content I have as well. It just won't open or download.

Today, I finally gave up waiting for anything official.

I put on an eye patch and got my down-loadable content to finally work so i could actually keep playing my game..
