Thanks Brutus for help. It turns out to work. Before, i uninstalled it but i didn't delete the program folder so far i remember. Now everything is fine.

Hi guys,
a while ago i download the the newest update 1.1.9 but when i am start FAF its appear a disabled login page with the error message that my FAF version is older than 1.1.5 or older and i have to download the newest update to run FAF. Its also appear the download link but when i reload the update its always the same message with the disabled login. Before i haven't any problems to run FAF
System: Windows 10
