Jacqueline,  while I think (and hope) that Mike M and Ron Lowe's advice will
resolve your problem, you need to be careful.
If the modem is an on-board device, on the MSI mainboard, and not a PCI card
add-in, then MSI may have their special driver, which should be obtained
from them.
While the generic driver may work well for the basic modem functions, some
special functions may require the MSI driver.

So while in the box, get the m/b model number, rev. number, etc, from the
silkscreened info near the center of the board, and compare it to the
Everest report to confirm, in the event this info is needed now or later.

HTH,
