Hi Clive, I am very surprised you cannot upgrade to a concurrent licence -- for many years this option was available with many Adobe products (and maybe still is?). Concurrent licensing allows you to buy licences according to the number of concurrent users, rather than the number of installed computers. (E.g., you can buy one copy, but install it on three computers, as long as only one computer opens at any time.) I'm not sure if that would be useful for you, or if it is available for small volumes, but it does (did?) exist.
James.
