Hello World of Minecraft staff, I have a problem.When i try to login via World of Minecraft Client it says "Unable to authenticate Your username/password may be incorrect or there are no servers to validate your login." Now I have tried to erase World of Minecraft and download it again.It DIDN'T WORK.I tried with diffrent versions of jafa (6 and 7).When i tried to log in I was logging in with my minecraft.net username and password,rechecked the password twice.It DIDN'T WORK.I even tried with MOJANG account.It DIDN'T WORK. HEEELP PLEASE!!
