I would like to return to a Proboards default them. I don't have it anymore on my forum. 

I want to start all over with a default Proboards theme. Thank you.

If you go to admin > themes > theme manager and click the "create new / import theme" button, you should see the options to create a new theme, copy a theme, import a theme, or get a theme from the theme library.

Select "create a new theme" and you'll be able to select the default PB theme to build off of (:
