Having a problem trying to change the login screen, When I download a theme archive, for example http://gnome-look.org/content/show.php/Raindrops?content=105866, I get the error message "Not a theme archive - File not a tar.gz or tar archive" when I try to add it to the theme options in Preferences -> Login Window.
Any suggestions? It definitely is a tar.gz archive, and I've tried several different ones and all give the same error. I read that GDM themes need to be changed to MDM themes, so I done that but that never helped so I guess that wasn't the issue... or rather, that would have been the next issue after this one
Cheers in advance
Running Maya with Cinnamon and an AMD 64 processor, not sure if that's relevant.
