I am enjoying the 3 day trial, running on my Surface Pro4 (windows 10). All seemed fine until the session centered around a café; it didn't work. Also, the microphone is not recognised. I ensured Adobe Flash is all in order and enabled for Fluenz. It works fine with, say, Skype. Today is day 3 and I am very keen to purchase but need to feel confident it will work perfectly with this device. Any help much appreciated.
