League of Legends won't launch - help please!

Lol was working absolutely fine yesterday - today after I started up my computer I clicked the icon and got just a flash of the LOL logo and then nothing for several minutes. I tried again and my computer told me there was already an instance of the launcher running. I checked my processes and saw the patcher was running as a background process using 0% cpu.

After playing around with it, restarting my computer, attempting to run as admin etc. I decided to reinstall. Still encountering an identical issue.

Any ideas?

For anyone still having this problem, I found another forum where Ad-Aware was blocking the patcher. Disabled it and re launched League and it started patching.

Anyone submit a ticket? I did but after the Submit button goes grey I can't confirm it's been submitted.

Yup, disabling adaware worked.

I'm having the same issues on my PC. I restarted to see if that would help, run as admin, etc. and nothing. I also am attempting to reinstall the game, but since it won't start up, I can't do that either.
