blue, they say the only thing they did was get new printers last November, which is around the time the problem started. An update keeps appearing, but they didn't install it (it is for payroll and merchant services, neither of which they use). They had "update" confused with "upgrade".

The XP computer is connected wirelessly - the other three are cabled into the Linksys router (a G router) and are Windows 7. Only the one computer that is the QB "host" and the XP computer can't share the program as they did. All computers on the network now appear on each computer. Thing is, when the bookeeper opens QB on her computer, she still gets the old data, not the updated stuff from the host computer.

They will need to contact QB to figure this out, I think. And that update may need to be installed.
