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,
Nick
