Adobe Illustrator 2020 Adobe Color Theme panel giving "Page failed to load" error on Windows 10

Hi Ana,

Sorry to hear about your experience. I'd request trying steps below one by one:

1. Restart your computer.

2. Try logging out of Creative Cloud and log back in.

3. You may also try resetting the Illustrator preferences. Please follow instructions below:

• Close all Adobe applications. 
• Go to Location C:\Users\user\AppData\Roaming\Adobe 
• Rename  Adobe Illustrator and Adobe Illustrator 24 Settings folders to Adobe Illustrator.old and Adobe Illustrator 24 Settings.old 
• Launch Illustrator from the Creative Cloud. 

**Please note that resetting preferences will remove all the custom settings and Illustrator will launch with default settings. This way all your old settings will be saved in .old folders and Illustrator will recreate new folders with default settings.

Let us know how it goes.

Regards,

Ashutosh

I've already shut it down several times! But it's still there
