Login issue

I am just using a 30 days trial version now and yesterday my laptop crashed while logged in to SketchUp. When I try to login back, I get the message “You are using SketchUp Pro on too many machines. Please sign-out from another machine, or manage your activations below.” It seem that my previous session is still active. How can I terminate it and log back in? I was hoping that over night the session may time-out and everything is back to normal, but it doesn’t seem to be the case…

Thank you!

What do you see below? A blue button?
Click on it and go to My products.
Then, click on ‘manage devices’

If you can’t see the blue button, log in on the top right of www.sketchup.com and go to ‘manage subscriptions’ on the same spot as the login.
