file.AccessDeniedException: C:\Users\YAO_\AppData\Local\Gas Powered Games\Supreme Commander Forged Alliance\Game.prefs

It’s your game prefs file (which stores the list of mods you have activated). You could try fixing the permissions on this file or you could delete it and run FA from steam to recreate it. Just know that this will reset all in game settings to default.

I have deleted all from folder C:\Users\YAO_\AppData\Local\Gas Powered Games\Supreme Commander Forged Alliance and it's work. Thanx
