If you're just wanting to run Litestep, you should use Omar's installer and update the build to RC3. LOSI is currently only in the test phase and is still being coded. If you feel it's not behaving properly, report it as a bug to the author. You can find a prefered bug template on the LOSI site, aswell as the email address to send it to.

edit - ok, and what fractal said. :D
