Hi, it turns out the API is very similar and I updated to a free version of the new API (100 calls per month so use sparingly!). Please try updated beta version of LD extension, version 1.2.30.9.
EDIT - I added LDGeography.APIKey to version 1.2.30.10 to allow you to use your own key, see https://countrylayer.com/pricing.
