hi guys,

coming here again because recently everytime when i trying to download something i get the message that i am not the system administrator..it also will not allow me to sign in as the system administrator. but i am the only user of this pc. then i did the system restore and with no luck. i have never experienced this in winodws 8 beta 64 bit in the last half year.

can anyone one come up with help in this? many thanks in advance.
