expansions dont show up

I got a new xbox and reinstalled the game. I havent got Rise of Zilart, Chains of Promathia or Treasures of Aht Urhgan. I installed WOG but when I go in to play the game its not there either. All the new ones that I bought through the game are there but just not the ones on the discs. I checked online in my profile and they are registered there - what am I doing wrong. You used to be able to check through the game but now it just refers you to SE and I cant find anything there.

Doesn't WoG require the previous expansions, so if you don't have them then you wont have that either.

I installed the game with the expansions, then WOG. but none of them show up... just the newer ones.

ok I re installed - they are there now!
