Your problem might be related to the system repair you recently did and some corruption has occurred. Before trying the following step, make sure she has registered the software and created a McAfee account. I suggest she try to uninstall McAfee via Add/Remove programs and reboot the computer and then proceed to use the MCPR removal tool found at the top of this page under Useful Links and reboot again. Go to McAfee login under your account and redownload and install the software again. If your issue persists, then you might want to contact Technical Support Chat for assistance.
