My Book (blue ring) shows up on Win7 computer but not on XP

My Mionet software went out of date months ago, and I finally uninstalled and upgraded, but when I installed the MioNet upgrade, the network drive is still not visible from the XP computer.  Both the XP computer and the Win7 box are connected to the network via a wireless access point.

Wrong forum mate, you need to go to network drives to get better assistance.
