With VDL being a single-user license (one user can install on two of their own machines, not shared with another user), you would purchase another license by simply purchasing another copy of VDL. If it's something you needed right away, the best thing to do would be to call the Tapspace office and we could give you the serial number over the phone once the purchase was made. The extra disk (with this serial) would then be shipped to you.
