License used on too any computers, but i have only one

i’m getting a message that there isn’t a seat available for my license. i have only one computer, but when i go to account management it says there are 0/1 available. I’ve moved my computer to another house, can this be related to not being able to access my seat?

Each seat should be able to sign in on two devices.
But, a sign in in another version of SketchUp counts as a separate device.

Thank you. This is likely the problem then, as i was moving from v2020 to v2021. i quit the SketchUp v2020 but still am not allowed to open 2021, getting the message that too many machines are accessing my license. How do i open my new version?

i see now. i’ll follow those directions and see if it works for me. thanks again for your help
