To download the license certificate, go to the customer area (orders) and click on the green button at the top right of your order. You will need a license certificate/cue sheet to make DVD pressings, for example. It certifies that the song is free of any collecting society rights (e.g., ASCAP, SACEM, SABAM, MCPS-PRS, GEMA, AKM, SUISA, GVL).
The license key is located in your customer area under orders on the right side.
The license key is located on the first page of the license document.
FYI: The license key is not the invoice number! The license key is a 15-digit number and letter combination.
This can have two reasons:
1.) If you have paid by invoice, the license key and the license document will only be released after receipt of payment.
2.) The order has been canceled (e. g. due to a failed payment transaction).
