I just updated to window 10 and this is happening. I'm have somewhat the same problem. When the launcher starts up, I can put in my password then click the sever but, then it pulls up a window saying, " Where is the game client executable?" and gives me a list of files. I have tried using the " dndclient", "dndclient_awesomium". Any help would be nice. Also the " DNDlauncher" it just restarts the GUI.
