Well, you remind me of something: since previously I encountered the problem of downloading the new version just as the very first screenshot in this topic. Before i reset my x-aviation password, I deleted my whole tbm-900 files(including uninstall.exe and other related files). Then I used another PC of mine to download the tbm-900 installer from the x-aviation to see if it worked. But I have never run that installer with that PC, because when I was about to do so, I just got your advice on resetting my password. So I just did as you said and downloaded the v1.1.9 using the origin PC. I don't know if it's because I downloaded the installer using another PC that caused the problem. If yes, i apologize for that. And would you please tell me if there's anything I can do to get my planes back? Thank you.
