Hi Nic, I ended up going back to the Samsung live support page (where I first started) and I now have to do complete system restore. partial transcript as follows.
- josh langley So in other words
Windows 8.1 is not compatible with this unit and the only way to fix it is with
a full system restore. - JhemIt is the compatible. However since this is a new update, we are still completing all
software and drivers downloadable for this operating system.
joshlangley Is it a matter of just waiting till new updates are available or that could be a while?
Jhem : The exact completion date of the updates are yet to be determined
