I tried installing a theme and it didnt work I guess because a window would pop up when I restarted the computer and it was asking me to install something. I couldnt figure it out so I uninstalled Litestep but now when I reboot nothing pops up except an explorer window. So what do I do?? Oh, im on XP...

when you install themes it asks you if you want to download some modules needed for the theme to work. you have to say *yes*, not reboot.
If you want to try again, reinstall ls, if you prefer to revert to explorer, use the setshell utility included in the installer (so you have to reinstall it anyways :P) and set explorer as shell.

and, if you don't want to read anything, and you just want it to work perfect the first time (which I'm just assuming from your "it didnt work I guess because a window would pop up when I restarted the computer and it was asking me to install something") then litestep is not for you.
now, to fix the other problem, run this: http://beyondconvention.net/ohussain/SetShell.zip

I know what you mean when it asks to install the madules, I't did that and that was fine. This was something different... Anyway its working now...

what if your hole desktop is screwed and you can get to anything, im on another user name right now but on my name i cant get to anything. i tryed to log in as admin and delete/unistall litestep but that didnt work, i tryed to do system restore and i cant because i have to be on MY acount to do this, i think i am completly screw, some one help!

under litestep you can use the recovery menu (ctrl+alt+f1) to get the run dialog, then do the sam i said in my first post. if you have problems with ls dont delete it, you dont need to uninstall it to set explorer as shell, in that way you can try it again to see if it works.
