Hello,
The installation hasn't messed anything. And, you can restore FS9 startup by uninstalling JFK and replying YES to the question "do you want to remove the addon manager?"
The mistake was probably made by your antivirus that has likely identified our module as a threat, and blocked it's update, or corrupted it trying to fix it.
I've checked right now, and all files are correct, both locally and on the server so, it's surely nothing wrong with the program.
Try to do the following:
- Unistall JFK and reply YES to the question "do you want to remove the addon manager?" Check you don't have any bglman*.* files in the FS9\MODULES folder. You shouldn't after uninstalling but, better check.
- Turn your antivirus OFF
- Reinstall, check that is downloading some files at start. Don't turn the antivirus ON, yet.
- Configure your antivirus to ignore the FS9\MODULES\BGLMAN.DLL
- Turn the antivirus back ON and try again running FS9.
