Hi guys,

I've encountered a weirder thing this morning because when i try to replace one file with another and it tells me that I need permission from admin. BUt i am the only user of this computer which is running windows 8 beta 64 bit. at the very beginning, it works fine and i am really love its sleek and quick operation. then i turned off user account manager and it still tells me I need the right permission.

I've never experienced this kind problem in windows 7 and XP. does anyone know what could be causing this?

if yo can come up a fix is much better. many thanks in advance.
