i recommend you uninstall it, and reinstall it using LOSI. LOSI is up to date, and i would highly recomend it. the omar installer is decent, but out of date. as such, it would recomend LOSI.

BTW, it's called a theme, not a shell. Litestep is the shell.

never had your problem, try installing the recommended dlls from ls-universe. they might be your problem.
