Start Menu folders no longer connected to corresponding user folders

Before (unsuccessfully so far) upgrading to Windows 7 In deleted (OK.
stupid, I know) both the Music and Pictures folders in my account. I have
now replaced them from my backup but now the shortcuts in the Vista start
menu no longer recognise them and remain empty.

I have tried to enter the location into the shortcuts but that's actually
blocked. I have checked the properties of the restored folders and they are
System folders just as before.

Any suggestions how I can reconnect the two?

Would love to ask Windows 7 questions but won't...

Thanks A.
