Hi, With Bruno Jesus, we create a hack to pass the ReadFileEx error for the Ubisoft Game Launcher (see bug #28119). I tried the hack with 3 games and they work correctly. But for two games (Assassin's Creed 2 and Revelations), the savegame does not works correctly. The savegame folder is here : "c:/users/berillions/Local Settings/Application Data/Ubisoft Game Launcher/savegame_storage/XXX/40/" These folders exist and the savegame files too but when I launch the game, the savegame is not found, I can only begin a new game. This is a message that i found in my +file log : warn:file:CreateFileW Unable to create file L"C:\\users\\berillions\\Local Settings\\Application Data/Ubisoft Game Launcher/savegame_storage/YmVyaWxsaW9ucw==/40/2.save.extendedmeta" (status c0000034) trace:file:CreateFileW returning 0xffffffff I create a bug report but i would like to have more information for this error. Thanks
