I have the IXEG 733 and the LES DC-3. I just recently purchased a new system from X-Force PC and migrated my X-Plane installation to it. I was able to update the computer ID, and both worked fine for a day or two. I then got the notification that Windows 11 was ready to install, so I did it. I hated it and rolled back to Windows 10. Now, every time I start X-Plane, I get messages saying Machine IDs do not match and License Data Invalid. I sent an email for which I have had no response, so I am asking for help here. Thanks!
