Just installed the new release of MSN 7 and other people using my computer are complaining that all their contacts keep being deleted, even though im not having any trouble with it...
I'm not sure about this, did you install MSN Messenger 7 final in a admin account? Not a limited user.. even tho i don't think it would allow you to install anyways.
Have you tried uninstalling and re-installing possibly in their account?
