Thanks Brendan.
My screen is laid out a bit different to your image but I've clicked on my name (which is to the left of the page) and hit the Password Reset option but nothing happens? No email received either.
While I was searching for info on a password reset I came across a thread about Hotmail accounts, maybe thats the issue?
The Google password protector (not sure of correct name) said I need to update password here hence why I'm trying to do it!
I'll try it on a PC tmrw to see if that helps.
