I want to delete my current tree from Ancestry.co.uk and upload a new one from FTM 2010. I'm unable to delete the existing tree because the website shows my password as incorrect. My understanding is that I need to enter my Ancestry.co.uk password, which I am doing. I just logged in and out of my Ancestry account and the password is working fine there but still the delete tree function will not accept it. Is there some other password required that I have overlooked?
