Not Enough Access Privileges error.

[Libtech]

I am trying to click on auto sync photos and its not working. I get the following error message.

"An error occured while updating the default player for
audio file types. You do not have enough access
privileges for this operation."

Also when I try to add videos to my library, they just dont show up in it nothing happens.

But I am still able to put music in my library and Ipod.

I have tryed reinstalling all Itunes + Ipod software.

I have tryed creating new Windows accounts with Admin privs, my accoutn has admin privs, I have also tryed on the actuall admin acount and its just not working.

Yet it works fine on my laptop.

Please help, im about to format if I cant get it.
