Windows Explorer won't open in my Administrator account

Alright, so here's the story.

I using my computer's built-in Administrator account to try and install one of those downloadable Appearance settings mods. For part of it, I had to post something in the System23 folder. It wouldn't let me do this, because the folder was read-only. So I opened the folder properties and changes it to not being read-only. It didn't let me finalize the changes because "program is currently using this folder". So I Xed out of the Explorer Window, and tried again. Same result.

Had I been a wiser man, I would not have tried what I did next. I figured that the only way it would work would be if I closed Windows Explorer. So I went into the task manager, found explorer.exe, clicked end task and. . . . closed windows explorer. :nope:

My normal account works fine, but in the Administrator account there's no browsing windows, no icons, no taskbars, no start menu, no nothing. Just me and the Task Manager. :upset:

I've tried using the Task Manager's Run function to run both "explore" and "explore.exe". Neither worked.

I've tried restarting it several times.

How do I get Windows Explorer to work again in the Administrator Account?:4-dontkno
