Fixed it.

This is so odd. My pin set for Track and Protect was e.g. (making this up now) 987654 and this didnt unlock the phone. but the pin i usually use is 2 digits longer. e.g. 98765432 (8 digits). This was too long for the password to be set but i typed it in anyway. So when I hit forgot password on track and protect it gave me the first 6 digits of that password. Which of course didnt unlock my phone BUT did give me access to the website for track and protect.

So i tried entering the 8 digit passcode and it worked. How odd and strange is this? Find it quite ridiculous.

Thanks for the help guys
