Hi so When ever I try play quake live on my internet explorer on my main computer I always get this "An instance of Quake Live is already running. Please close this web page.". It started about a month ago when my quake crashed while joining into a game and since then closing all browser instances including the program tree through task manager it still gives me this error and since I turn my pc off when I go to bed every night I would of thought it would be working by now?

ps when I log in from my other computer it works perfectly fine no problem however I have given that pc to my sister since I don't need it and it is fairly out dated.

any thoughts on how to fix this?
