New Expansion QuestionFollow

I have purchased and download the Minotaur expansion and signed on with one my accounts and played successfully.

However, I also have three other accounts when I go sign on to the new client with one of them I am being asked to again purchase it for $19.99.

Now I have the executable setup files in my computer, is it just a matter of running the setup again and signing into with other accounts?

I dont remember purchasing 4 Catacombs or 4 of the next expansion in the past.

Anyone have any insight?

As far as I know, you've always had to enable each account with a unique expansion key, therefore, you've always purchased expansions for each account (unless you started an account with a multi-pack (i.e., platinum edition, etc.)).

I believe you can use your other accounts without the latest expansion by using the old icon to log in. So, if one of your accounts is only updated to Catacombs, simply use the Catacombs icon to log in.
