they really need to fix that line 913 crapola stat...I didn't get it on that particular edit but it shows up in other places...extremely annoying...
edit: you might try giving your clientscript folder at least a 755 chmod setting or even 777 and try it again. I seem to recall having trouble setting up the vbulletin_css folder initially as well (that should be placed inside the clientscript folder)...
