Why won't my Gear S2 connect?

AC Question

My Gear S2 won't connect, HELP.

Just bought a £250 Gear S2 and tried to download the Gear Manager App which states it is already downloaded on my phone when I try to access it from the app store. In place of the 'install' button is 'open', however it isn't 'clickable' if that makes sense. Usually if an app is already installed you can go directly to it from there, however when I click 'open', nothing happens.
