I upgraded from Halion 6 to 7, and went through the licensing system update, but H7 did not work. Steinberg support took about a day to fix something on their end, and then it was working. H7 is s nice upgrade. Even if you did all the steps to update the licensing system and transfer from the dongle, you may still need to contact support if there is a glitch over on their end. They did it in about a day for me. Hope it works out for you
