Hi clairemummy, from your screenshot it looks like you are currently using Little Reader v1.6 - it's an old version which doesn't have the same feature as the one described in Lappy's post.
Here's another way to find your license key(s):
1. Sign in to your BrillKids account
2. At the top of any page in the BrillKids website or forum, place your cursor over "Account" (you'll see this just beside your forum name)
3. In the menu that appears, click "Purchases"
4. In the next page, click on "[2] Curriculum & License Key" under Little Reader (you'll see this in the left-hand menu)
5. The next page will show all your Little Reader license keys (for English, Chinese, etc.)
If you still can't find your Chinese key in your account page (after following the steps above), please check your Chinese Curriculum box or CD case - there should be a sticker or card with your license key printed on it inside the box or CD case.
If you need further help, do write to us at support[at]brillkids[dot]com and include these details:
> The email address you use for your BrillKids account (if you've created more than one account, do mention all email addresses)
> BrillKids order number for your Chinese Curriculum purchase (if you bought it online at the BrillKids Shop)
