I had not opened Xplane in a couple of months. So when I received the upgrade offer I decided to To update Xplane first to the current V10.42. After the update I ran X plane, and after Xplane loaded the SMP 2.1.1 activation screen popped up an just keeps spinning (callback error from the server). Do I need to fix the activation issue or can I just uninstall v2.1.1 and goto v3.0? Thanks Tim Attached Log.txt just in case. Log.txt
