Register HGO PowerPacks:

NOTE:  "Register" means paying for it.
              "Activate" means putting in a code that you bought.
               If you already paid, you need to "activate".
               To do that, go here.
               (And if you did not pay yet, continue below...)

  Please click the PowerPack you want
       to register from the list below.




When you click a link above, you will see a page describing the
PowerPack you have selected, so that you can be sure that it is the
one you wanted to register.  On that page will be a "Buy" button.

If the PowerPack you select above is not the one you meant to get,
simply click "back" on your browser then click on the correct one.
