Thanks for your post and welcome to the forums. It's great having you on board with us in the Community.
I'm sorry to hear that you are having an issues resetting your password to log in to My Virgin Media. The first thing I would try is deleting the cache and cookies on your browser. Once you've done this try the Password Reset option again.
Failing this, come back and let us know and we can see if there is something else we can do to help.
