We've changed how license keys are issued.
In N|Solid v1.4, we streamlined our getting started process process by moving license key requests entirely within the N|Solid Console.
We recommend updating to a newer version of N|Solid. You can download the lastest version at downloads.nodesource.com.
If you need a license key for N|Solid v1.3, please contact firstname.lastname@example.org.
