is this windows 95/98/ME or windows 2000/XP? that's going to affect how much of a problem you're going to have.
if you can get to a command line or a run box (like if you have 2000 or XP, from the taskmanager), you can use "c:\litestep\litestep.exe -uninstall" to put everything back

never heard of that errror message. What build of LS did you install?
