Good to see the issue has been resolved!
And for future reference floof, you can always use Notepad for any .material file you want to edit, such as for presets. Every computer should have the app pre-installed (at least for Windows), and a simple search in the start menu should find it for ya. You can set all .material files to open automatically by going to one and editing what app it opens with in the Properties (right click on file>Properties>"Open with...").
A staffer should be along soon to lock this up for you!
