Hi Buckleysmom, follow the link below to the login page:

then log in. The page that you are presented with should say account status unregistered. Below this are four choices. The second one says:
Redeemable booster packs
Click on this and it will take you to the page where you can download all ten, though you have to do it one at a time. Each booster pack should contain 10 cards. Click on the button that says Redeem
The page that it takes you to has three buttons to the middle right of the page that say auto arrange, reveal all and redeem another.
Your first boosters should be on the page, click on auto arrange to spread them out, then reveal all to see what you have, then click on redeem another, continue until you've redeemed all ten packs.
You will be able to utilize these units later on when you start to build your land armies. Not all of them can be used at the beginning as you can only have 200 units to manage at the beginning of the game, though you can customize your armies, once you can afford to keep them.
The units can be utilized/activated by clicking on the main building in your city which brings up a small window. Click on the third icon to manage your units. I'm not able to access the game at this time as the servers are down, so can't describe exactly what the icon looks like; the first one is to manage the peasants in your nation. Clicking on that one enables you to allocate the ones you have (which is 10 to start) to specific tasks such as building or farming, though farming wont be available until you've build a farm.
There is a button that opens up a menu which shows you all the units you've amassed from the ten booster packs, of which there are 100 (10x10), though some units such as the archers and pike men will have been repeated three or four times as these are your basic army units that you'll need more than one units worth (I unit of human pikemen for example is equivalent to 25 men, but if you select elven archers then there will only be 6 men (or women, lol) Though before you start to develop your standing army, you need to develop your nation so that you can feed and train your armies. :)
