Extension installation error

Trying to download Artisan Organic Toolset and when I click on the “Install free trial” link I am either taken to the Sketchup help page on how to install extensions or I get the following message:

**Something went wrong during the authentication process. **
Please contact system administrator. Reference ID: 656520f1-407b-47a9-a197-d9ccc71343d3
I have had similar problems with other extensions.
Can you help?

Can you try logging out and in again inside SketchUp, and see if this clears up the issue?

Best Regards,
