@ManiX +1 to that! I'm in the same boat(Digital Fun-Pack with the Strategy Guide- and Expansion-Addon).
Would have been nice to simply get the Royal Edition, instead of having to go thru 2 different places, manually downloading each add-on.
If they can offer a better solution(manual upgrade to royal upon request for those w/the addons?) thru customer service, as you say, all the better. But oh well, in any case still really excited; can't wait to play PoE! Thanks for all your hard work Obsidian!
