HI Vern,
I see this is your first post, so welcome to the forums. You should be able to restore your workspace and see the Ribbon. You can also type RIBBON at the command line and that should open it up.
Also I'm going to move your message to the AutoCAD forum as this is the A360 Forum. You want to post AutoCAD questions in the AutoCAD forum.
Hope this helps and have a great day.
