Hi - I have dowloaded AirDroid on both my Moto XT1068 and my PC. I can access my phone through the PC account (read messages, view contacts etc) but my phone does not recognise that I have signed in to my account on my PC. I want to transfer files from phone to PC (i.e. to bak up my contact list) but can't because when I hit the "AirDroid Desktop" button it says "No computer found with your account" even though I am signed in to that account on the PC. Please can you help?
