Hi PyeHzqOd,
The NLG blockchain is unfortunately no longer supported by our external Altcoin Wallet API provider.
You can enter the transactions either manually on the "Enter Coins" page, with the "Excel Import", or with the "Custom Exchange Import". Both are very flexible and customizable and data can be uploaded in a bulk action.
We apologize for the inconvenience this may cause.
Thank you for the info. Too bad to hear this. The API was very handy for the witness/POS accounts.
