Hi Anthony. Welcome to justanswer.
Do you see Forgot Pattern option listed on your home screen.
After 5 attempts of unsuccessful pattern, Forgot pattern will appear on your lock screen. Do you see it. If not then draw any pattern till 5 times and you will get a warning. Do you get the option? It will be on your lock screen.
CLICK HERE and then press I Agree. A file will get downloaded. Just open/run that file to start the remote desktop session.
