Hello, like some others here, i cant start the game anymore. Win 10 I tried: Edge, Opera, Firefox no way: Allways get the INSTALL Button. Window Defender deactivatet ... hell yesterday all was fine. Cant you setup a normal game login? I have this annoying Problem 2-3 times the week. But this time i can try again and again, allways: INSTALL INSTALL INSTALL ... and yes, i have only installed this game client. L2 Classic. Nothing else.
