I’ve installed the web player and restarted my browser. It says that the installation was successful, but it does nothing. 
Any solutions?
you installed the player in your browser not a game. it works like flash - it’s a plugin for your browser. you need to find a game to play through it. some demos can be found here:

I know, I’m running Mac OS X 10.2.8 and after it’s installed it opens the browser with the test page. Which says, “Click to install plugin.”
you didn’t get the box you can spin and blow up? bummer. don’t know on 10.2.8. should work i think. wait for otee to respond…
