Hmm. Can you try to start it then go to Start Menu > Type "Event Viewer" > Windows Logs > Application
You'll probably see something from AeroScenery in there. Paste it in here and I'll take a look.
If you go to your Windows Documents folder > AeroScenery > database, rename areoscenery.db to _aeroscenery.db. Try starting the app again and it'll create a new database.
If that does work, could you zip the _aeroscenery.db and attach it here as it'll help me debug what's gone wrong.
Thanks.
Thanks for the message! I see 3 events created on "Event Viewer" when I try to load AeroScenery (posted below).
I tried uninstalling AeroScenery and deleting the whole AeroScenery folder from Windows Documents folder. When I reinstall the program and try to run it, it does not create the areoscenery.db file, only a areoscenery.txt is created. I'm uploading this .txt file as well.
The attached areoscenery.db file seems to be from yesterday while it was still working. I dunno if it will help you.
What changed in my computer since AeroScenery was working:
- I moved Aerofly FS 2 installation to an external USB HD (F:) using Steam's "move installation" function.
- I configured AeroScenery to create sceneries to that external F: drive.
- I turned on the windows suggestion to fix blurred apps. (I turned it off now)
I hope that helps. Tell me if you need any more files. Thanks for the patience!
PS: Is there a PayPal I can donate to keep this project running? I would gladly donate.
