SKU stops working when 3D warehouse downloading

When I try to import some 3D model from 3D warehouse SKU does not respond to any commands. So I’m forced to restart the PC.
Did someone else get the same problem?
Maybe something related to Win10?
Many thanks

Many thanks for your suggestions!
I’m still using SUPro2017, and I’m wondering if updating should be necessary for me (I am a woodworker …).
3D warehouse is for me a great source of components I don’t build by myself, so I will follow your indications.

When you find an example model that doesn’t quickly appear in your scene, can you try the same model downloading into a new document?
