Hi All, This is my first post and it has been prompted by an update. I should have learned! My Tablet PC was murdered by a Win10 update. Now scrapped. Today's experience is with the 1.70 update. Beware!!! When opening RM today the update appeared and I (foolishly) said YES. Mistake! It updated fine and showed in the small window at the bottom of the screen. However up popped a window which showed " Cannot handshake with elink. Chack that elink is V1.07 firmware. Checked that, and it was. Updated firmware again using elink107 in the RM folder. Update went OK. Problem still the same. No handshake. Grrr! No elink operation at all !! Have contacted Hornby and RailMaster and am awaiting a reply / resolution. I don't know how to add screenshots yet. Just beware of this update. Anyone with similar results post here!
