Hi John,
So trawling back through my emails .....
You were one of the very first early adopters for the shield, I now recall.
Your license was pre-database so did not appear!
I have now manually made an entry, which will allow you to renew.
What you may want to consider, is upgrading your HW from RPiB+ to RPi2B+
This remember will give you the additional features
- Mode-S
- Mode-C
- Audio Messages
If you email/PM me directly I will swap the license over if you decide to switch to an RPi2B+
So you can now renew your key by going to

Thx
Lee
