I just disconnect my wifi, launch the application and then turn on wifi again. it works for me that way. but DO NOT hit the 'home' button on the software otherwise it will ask for key again and you'll loose your data (as I just did today) and came on here to see if anyones got any more keys. but happy to turn off wifi and back on to get the data i want. hope it works for you. using windows 10 here. did see that someone went into their settings and done it via 'networks' option to disconnect but just by me turning of wifi works. give it a go.
