In an effort to keep this thread alive. Submitted an email support request as well.
Having the same problem with the new Windows 8/64 notebook I got. Same issues noted by jsjgamer & others.
WDLink shows the IP addresses of the 4 Mybook Live drives on the network (1tb, 2tb, & Mybook Duo) but none of the shares.
Still have good access by the WinXP and the Win7/32 machines on the network but I expect from now on new machines will be Win8/64 to stay with the current OS/Hardware.
Will see if I can find the Dashboard username work-around that Deutch mentioned. Since I’ve got the shares permissioned based on family members this isn’t an ideal work-around.
