Nokia E7 phone

[buddylab]

I have just bought a Nokia E7 phone and am trying to assign specific ringtones to my contacts. The user guide says to go to the desired contact, press options- edit- go to ringtones, select ringtone and enter. I did this and it assigned the tone to all my contacts. I have also downloaded ringtones from the Ovi store and that is even more of a problem in trying to assign because that they are not appearing on my ringtone list but on my recent download activity log on Ovi. Am I missing something simple here? Can anyone help please?
