N900 central

I have installed and installed twice but the backup and retrieve buttons are still grayed out only one pc is showing on the smart ware, the storage is so far unusable. Please

Half your luck - I can not get past trying to sign in with a user name and password - will not accept the default and WD support can not help me - great I have only had the N900 for one day and can not get it configured - loving this product love the “3 minuits setup” as stated on all the spin
