The Trigger Perpetual Single User License is supplied in the form of a USB security key (dongle). This needs to be plugged into a USB type A port on your computer. You may remove the dongle from your computer temporarily and Trigger will continue to function normally, for up to 5 hours. However whilst the dongle is detached you will not be able to save your project.
If you have temporarily mislaid your security key (dongle), it has broken, or you have one on order, you can buy a temporary (software) license through this website. This applies to registered Trigger license holders only.
