Vista

Hello
I keep getting: (5, 'MoveFileEx', 'Access is denied.')
I have full Admin rights, this error message (159 times) only started appearing after Bleachbit last upgraded.
Any ideas as to why?
Thanks, Lief

Vista Home Premium on Gateway M-6827. I can clean as Administrator but not as normal user. Have tried extensively to work around including shift+right click+administrator in normal user which only cleans administrator. How to clean normal user in normal user or Administrator? -Thanks!
