Time Machine and WD MyBook Live

My wife's Macbook Pro won't finish a back up, it keeps erroring out. I deleted her user account off the WD MyBook Live and made a new one thinking something was wrong with her account. So I made a new one and now she is getting this error (attached) My Macbook Air backs up just fine and hers messed up all of a sudden.

The MyBook Live does backups over the wifi network.

She has tons of stuff on her HD and I don't want her to lose it.

Finder > Shared (MyBook Live) disconnect all users then reconnect this will also happen on an AEBS with a USB drive from time to time for some unknown reason .

If you are using an Airport Extreme you can access the disk and select disconnect all users and if its a shared drive you can use Finder to select disconnect all users. You did not state what router you were using it may or may not have that ability.

I'm using a recently purchased Belkin router (at work so I can't get the model right now)
