New problems, with Win 10 firewalls and windows antivirus, got L2.Exe lost, which is pretty nasty. Deactivated anything on windows (which is not ok, but well, the life is a garbage), but guess what: The updated don't put the folder back, and it should, and the updater's "start game" button don't work it either (normally, cause no exe in the system folder). After all that, a sure thing: The updater reset all the game settings to default, which is a crap for game-play efficiency. We should try avoid the "one problem after another" issues like this
Need to re-download the client, obviously
