The game doesn’t save Sound and Video settings. In addition, each time I start the game it shows me an intro video like when you run the game the first time. However, it keeps my key bindings even after full game reinstallation.
I can not find d3prefs.txt on my system.
I found this problem after the latest update was installed.
UPD1: Found the next error in D3Debug.txt:
ERROR: Couldn’t create preferences directory. Path is locked or missing?
UPD2: Controlled Folder Access is off. I tried to enable it an gave access for Diablo III no results.
I tried to create Diablo III folder in my Documents. Copied there the D3Prefs.txt file from my laptop - no results. When I reset in-game settings from Battle.net app it removes the copied file, but the game still can’t create preferences directory.
