DLC: Offer selected is not valid [ Edited ]

[deusherba]

In one playthrough I couldn't start Return to Ostagar and now in my current one I can't start Warden's Keep. The game shows a [Download New Content] dialogue option, however selecting it only gives a message with "Offer seleceted is not valid".

Haven't found any solutions with this particular issue.

SOLUTION: I hadn't tried sufficiently. Downloading both DLC and offer files then installing them with daupdater.exe solved my problem.
