the game wont work for me

[Deathtron55]

i think it might be because my computer was broken and my uncle did something to it but now the game wont work so i dont know what to do.  it just comes up with a grey screen when i try to load it.  Does anyone know what i should do?

Does the downloader come up? If not go here; http://www.runescape.com/game.ws?j=1. If nothing loads then Java isn't there, and you need to reinstall it. http://java.com/en/
