Sure, the problem was that I couldn't play because I accidentally checked the box that said "Always associate aos files with this app" (I'm not sure if this is what it actually said, it's just what it would translate to english, for I am german)
This is how you fix it if you use Firefox: Go to options -> Application tab, and search for the file called "aos".
Then you just have to click on the right drop-down and select the App, which you wish to use.
