Why can't I look in my Vista Documents and Settings folder?

[Dutch Guy]

If I browse to my Documents and Settings folder in Vista and try to open it I get this message:

I haven't changed names, did not add a person so I am stumped as to why this has happened, what can I do about it?

[edit]The same for Local Settings, My Documents and a few more [/edit]

I went searching on the net for this and found that the user folders are here: C:\users\[username]\AppData\Roaming\Microsoft\Windows\ but I am at work now so can't check to see if that is the case.

All I want is to see the temp folders and organise the start menu, why does it have to be hidden so far away
