Hello @user @88YR OLD CODGER
Welcome to the LastPass Community.
I checked the logs and it shows you are entering an old master password. Since it shows you know your old master password, you may revert to it by following the steps outlined on the following link: https://lastpass.com/revert.php
Please let us know if there is something else, we can do for you.

Thanks for the reply, problem is I am using the latest password on my desktop PC as on the laptop and the desktopm works fine? could it be some sort of storage of a master password somewhere on the desktop? If I change to an old master p/w on the laptop would it mess up the p/w on the desktop or can you have two masterp/w for each machine.
Thanks.
