Paid up but cannot connect more devices to Key
I installed Key on a desktop machine and paid for the synchronizing feature on that same machine. Then I got a confirmation email that everything was in order (read on a laptop elsewhere).
But when I try to connect more devices, I can generate the connection code on the original desktop (Windows 7) BUT entering the code on my Samsung Android phone consistently fails. The program urges me to check my code and my internet connection even if the code was correctly entered (several times) and I have a working network connection for the desktop (network cable) and the phone (wi-fi to the same ADSL box). No better luck with my laptod, either (Windows Vista, wi-fi at a different location).
What is wrong and how can start using what I paid for?
