Hey delok - first of all, thanks so much for taking the time to respond to me in here - really appreciate it. I was a bit slow to reply to you as I was waiting for Line6 to get back to me via support. The good news is that they made some changes at their end and now my Native plugin is up and working as expected. Interestingly I never had the option to enter a code at the bottom right like you described but in the end, Line 6 were really helpful and got me sorted before my trial time ran out. Thanks again for your help in here, and thanks also to Line 6 for getting me up and running!
