New Release - WD TV Live Firmware Version 1.06.43 (1/17/13)

Youtube Leanback hangs indefinitely at the YouTube-logo&white bar screen when loading. 

(in this latest release, as in every Firmware (beta) version sinds the introduction of Leanback on the Live.

As in: normal, ‘old’ Youtube worked perfectly, Leanback has never gotten beyond the point of just showing the Youtube logo on a black screen)

Please advise on how to solve this, so I can finaly use YouTube(LB)?
