Trying to install SoA on second computer

[Totema]

I've already installed the expansion on another computer (and therefore have the service linked to my content ID) and downloaded all recent updates onto this computer, yet whenever I start the game up it insists that I don't have the expansion installed. I think I have to download the expansion itself, like when I first bought it, but I'm not given this option and it looks like I have to buy it again. Can anyone help?

Ah, I got it... I simply had to use the link they provided to track my order, which let me download it again. Handy! Everything works as normal now.
