Rundll23 will not work

I have a problem with my computer, i wanted to change the look of my computer, So i installed Vista Glaze, then i patched the files.
Then i dl'ed AlienGuise and put on the theme, then i went to go

Control Panel> Appearance Personalization> Personalization> Themes

it comes up with a little window saying Windows host process (Rundll32) has stopped working.

Please help.
I would like Rundll32 to work again. >_<

 

Sounds like the skin you installed corrupted a critical system file. Insert the windows installation CD, and do a repair installation. You won't lose any files, and it will reinstall just the file necessary for windows to function.
