Wd my book live & LG TV not displaying files/folders

After having our my book live an lg TV (42lw650t) working OK, we swished over to the DLNA input of the TV to see a message saying “empty folder” where it used to display all the folders etc

We have powered everything off, factory reset the TV, checked for updates on TV & checked al connections we cannot find a way to see the files.  We can, however, see all the files and folders on a mac, pc & the wd2go pro app on ipad

Is this something that wd need to fix?  The whole point of buying he nas & the TV was to play video files straight to the TV.  It will be a at waste of 3tb if wd cannot sort this out

We believe the issue has started since a firmware update to the nas earlier today…

Try pressing the reset button on the back of the My Book for 4 seconds.

found it! just to to WD book setting under media tab go to TWONKY MEDIA and press resbuilt!
