1) From the ArtRage ‘Tools’ menu, choose ‘Browse Content Folders’ and choose ‘Root Content folder’ from the submenu.
2) That will open an Windows or Mac file browser.
3) Exit ArtRage, but leave the file browser open. (This is important because ArtRage needs to be closed or it will re-write the preferences file with the incorrect information…)
4) In the file browser, navigate upwards one level – to the parent of the content folder.
5) This should be the location: C:\Users\<your name>\AppData\Roaming\Ambient Design\ArtRage
where ‘your name’ is your windows username.
6) In that folder will be ArtRage7.prs (or some variation depending on the version of ArtRage).
7) Delete ArtRage7.prs
8) Restart ArtRage and all the panels and preferences will be at their default.
