Ok, so I downloaded Litestep that came with the Simplicity Theme. I got back my Explorer theme because the other one was too confusing to use. I want to use a new theme, but I dont know how to change my theme now. I installed one from this page, its called Lightning Speed. Can anyone tell me how I can change my theme to the Lightning speed? Thanks in advance.

1) "Oh man, im so confused" is not a proper heading for a post.
2) Simpicity theme comes with LS Installer by Omar, not vice-versa.
3) Explorer is not a theme, but a shell.
4) => You don't know how to change your shell.
5) Switch to LS and use LSTS or LSCP to change the theme (if you installed the theme correctly)
6) np ;)
