When Windows 7 Boots up to the login screen and my Yubikey is inserted I get the OTP Prompt but most of the time I get another prompt that asks for the OTP again and on Pressing the Yubikey Button it gives an error message saying'Manual Entry is not allowed' or something to that effect. Upon my second attempt it tells me I have entered a wrong OTP and I have 3 attempts to get it right or Rohos locks the logon key software.
