I do recall something saying that you need to uninstall adobe air and pando media booster along with LOL when you want to reinstall the game. There is also a way to backdate your adobe air version so it re-patches.

I wouldn't go as far and doing that with once the problem occurs, but use it as a last resort after a day or two were the game still doesn't work.
