You probably need to install Java on your PC. The easiest way to watch playbacks is to view them in the ANdroid app. Go to More Options -> Finished Games.
You just reminded me I have never tried to watch playback via my PC! lol. It works as I already have Java installed. Alas it doesn't work on my Android tablet where I play the game. But if I really want to view a game I have the option now via the PC.
Premature there. It started to run but was stopped saying the application is blocked. Can't lower the security settings any further to allow it to run.
Bingo. Hadn't tried going through options. I know you mentioned it before but thought that was how I normally tried to access it. Then realised perhaps it wasn't.
Thanks. Might help me improve my game watching the tactics the 'masters' employ. ;)
Android java is not byte code compatible with windows, so playback in the browser on your android tablet will never work. On your PC it should work. Add the website to the trusted sources in your java options.
