Hi Antoine,
Many thanks for your reply.
I already have V2 of Jupiter-8V which works with my existing licence. The licence is stored on my USB dongle and appears as "Jupiter8V2".
I cannot, however, use V 1.1.1 of Jupiter-8V because it does not recognise the licence and displays "Application 'Jupiter-8V 1.0' has caused the following error: eLicenser(s) contain(s) no valid license for this application."
The V2 licence is not compatible with V1.
