I need help working standalone Flash Player

Standalone Flash Player is not working for me, maybe I'm doing something wrong so I need help. So I open Standalone Flash Player and I go to "file" on the top left corner, then press "open" and is says to "enter the World Wide Web location (URL) or specify the local file you would like to open, so I copied and pasted the tanki home page website url >"http://tankionline.com/en/"< to the field it told me to ^. and nothing happened so I need help :D
