Haulix promo senders set download and streaming permissions on a per-promo basis. If you don't see a download button, then one of two things are happening:
1. You used up all of your alloted download attempts. If this is the case, submit a support ticket and a Haulix team member will reset your downloads or contact the respective publicist and request additional downloads.
2. The promo is streaming-only. Some publicists choose not to offer downloads with their promos. To find out how a specific promo works, please contact the respective publicist and request a download.
