Hi Rob,
for the commercial aspects (to get an Embedded Wizard 9.30 license) let us continue the discussion via email - directly to us or via the distributor.
Concerning the technical aspects, let me try to answer your questions here: In principle it should be straight forward to upgrade from version 9.30 to version 10.00 as we always take care on compatibility. However, the other direction is not supported. Afrter you have modified your GUI project with a new version it is more or less not possible to continue your work by using an older version.
Best regards,
Manfred.
