Problem opening link to a shared design sent by email

I am a complete newby and have joined Sketchup in an attempt to open a link to a design emailed to me. Error message reads -
Hmmm, the model was not found. It might have been deleted, or it might have been made private.

Can anyone help please?

Is the model shared on the 3D Warehouse ?

If so the author needs to share it with your user name. So give the person who shared it, your user handle “shinetrudi”.
