Not able to access shares WD Live HUB

I am not able to access my network shares from one of my networked PC’s.

My Network setup:

WD Live HUB - wireless connection

1 PC running XP - which is the one that I can’t see on the WD Live HUB

1 PC running win7 - which i can see on the WD Live HUB but doesn’t have the files i want to view.

all running though a Cisco wireless router.

Any help would be great!
