Hello Nick,
You have received 3 licenses for VE PRO 5 and VI PRO, so that you can use this software on up to 3 machines... Did you distribute the licenses accordingly?
Just to avoid confusion: Each Vienna Instruments Collection comes with 1 license, so it can only be used on one machine at a time.
Does that help?
Best,
Paul
