I tried using Chrome and then, when that didn't work, the latest version of Firefox.
By the way, I meant Fitbit Surge, not Flash Surge
Google embeds Flash Player in Chrome and there is nothing to install. If you have the latest version of Chrome (44.0.1403.107) it has the latest version of Flash Player (188.8.131.52)
Do you have the latest version of the Flash Player for Firefox (184.108.40.206) installed? You can check the version installed by going to http://www.adobe.com/software/flash/about. The Version Information widget will display the version installed.
If you have Flash Player installed, please ensure it is enabled. See Installation problems | Flash Player | Windows for information on enabling Flash Player in the various browsers.
Thanks for your quick response. I'll try your suggestions and let you know how it goes.
