Hi! For the renewal please contact sales@ pd4ml com – we’ll provide you with the instructions and the order link.

With PD4ML v4 license you’ll get a license key, which is valid for all PD4ML versions released before the maintenance period expired (3 months since purchase date for single PD4ML licenses and 1 year for others).

If by accident your build script pulled the newest release from PD4ML Maven repository after the maintenance is expired, it is going to switch PD4ML to evaluation mode. In the case you would only need to remove the version and download the one released before the maintenance expiration.
