MSBN.msi

Had to RESTORE my ME Laptop. After that could not access
my Wireless Home Network. Window installer tells me to
find Installation Package "MSBN.msi". When I try my
original "Setup and Network Utility" CD, it tells me "it
is not a valid installation packmage" and that a later
version has been installed.What can I do to get my Network
access back? I can access wirelessly Internet, other
computers can access my laptaps wired local printer, but I
can not see or access any body else.
