1. The Active Scripting is disabled, Go to Internet Options -> Security -> Active scripting (near the bottom) -> Enable -> OK. Restart the launcher.

2. Go to your projects folder (Default path is C:\Riot Games\League of Legends\RADS\projects) and delete the lol_air_client, then restart your patcher.

3. Go to your projects folder and delete the lol_launcher folder inside, this will reset your patcher completely.

4. Try turning off your UAC in Windows 7/Vista (does not apply to XP) http://na.leagueoflegends.com/board/...ndows-vista%2F

All you need to do to solve this is to type "thereisnourflevel" while having the lol.launcher "on the top" of all your running programs.

When I had this trouble, it had something to do with Norton 360. Everytime I logged in on the computer, some kind of error occured. But it couldn't be fixed automatically with Norton 360, so all I had to do was to go to the support website, follow the steps, and it was all fine.
