Well, if you only have one user on that PC, then you are most likely an Administrator. Changing permissions can be tricky, but it's easy once you do it:

> Right-click the folder/file you want to modify, and select "Properties".
> Go to the "Security" tab.
> Make sure your name is listed at the top as one of the names. If not (and you are in fact an administrator), add it (Use "Add" button).
Assuming your name is there:
> Click on that user (to highlight it), and look at the list of permissions at the bottom of the window. Make sure "Full Control" is checked.
> Click "Apply" and see if that worked.

If that doesn't work, go back to the "Security" tab.
> Click the "Advanced" button.
> Click the "Owner" tab.
> Change the owner to your name.
> Click "Ok"
> See if that worked.

If not, or you get any errors, helping you would be beyond what I could do on a forum.
