Thanks for your support, I'll look into it further. We'd better bury the hatchet.
My complaint was based on no response from the popup "Welcome to X-Aviation Support!" on the X-Aviation website. With that I could ask for help to solve my problem. X-Aviation did not respond to this, even after several attempts. That frustrated me...
Another possibility is the forum, which is excellently managed by you, Cameron. I had forgotten that at first, so my apologies for expecting support from the website first and then from you. Thanks again for your patience.
Another problem is that only the Avitab frame appears and not the screen. Do you have a solution for that?
