after I'm typing in my username and password the window "connecting" is popping up like normal but it isn't connecting unfortunately. What happens is I'm getting another window saying: "This account needs to be converted to a battle.net account. Please (click here) or go to (url) to begin the conversion."
Any idea what might be wrong? I had some problems with going fullscreen mode so I deleted the folders WTF and Cache. So probably some command lines are missing in config.wtf that might fix the problem?
