Over the last year, Stardock has been working tirelessly to improve the Support Site. I can tell that many hours have been spent to update all the information available to help you navigate thru any issue. The site is fully searchable making it easy to find the help you need.
The Main Support page is located at https://support.stardock.com
Or you can just click the Support tab in Stardock page header.

Specific Software help is located at https://support.stardock.com/page/software

Many thanks to Stardock for working to provide first class support for their software.
