My Book World Edition II(white light)

hi guys, my NAS drive (My Book World Edition II(white light)) appears to be outdated as it is no more listed on the Knowledge base and Troubleshoot web pages of WD. I have a problem where the NAS is not getting backed up although I can access the NAS and its contents using Finder. When I open WD Anywhere backup the backup is shown as 'Disconnected" I am using- OS 10.10.1 Yosemite My Book World Edition II(white light) attached to my router (brought new last week) WD Anywhere Backup 2.5 (which is the latest version for my NAS) I have little knowledge in networking and searching for solution on the internet did not yield any fruitful result. If any one can help then I would be very grateful. Apologies if the post is in a wrong forum as I can not find appropriate forum dedicated to my NAS model
