Nevermind, support staff gave me a solution, just had to do the IE settings thing and disable peer to peer. i can finally play

Can you describe how to repair it? Im from the same place and having the same problem. It would be usefull for me, please

The support staff sent me this and it was the only thing that worked
1) Make sure your windows clock is synced:

2) Make sure your Internet Explorer Options are properly configured (Updating to IE9 and running the Microsoft fixit file are the most common fixes from that guide):
http://support.leagueoflegends.com/e...roubleshooting

3) Turn off Certificates in IE, IE Options > Advanced > Restore Advanced Settings, IE Options > Advanced > Uncheck "Check for server certificate authentication"
If you have a more updated version of Internet Explorer you may have to uncheck these settings instead:
"Check for server certificate revocation"
"Check for publisher's certificate revocation"
"Warn about certificate address mismatch"

4) Disable Peer to Peer transfers from the Gear menu in the top right corner of the Patcher

5) Uninstall Pando Media Booster

6) Verify that Internet Explorer is not set to Offline Mode (You can check this through the File menu in IE)

If your issue still persists after all these steps, another process may be interfering with the smooth operation of League of Legends. Can you please take the time to provide me with a list of your running processes? We have a detailed guide explaining the process here:
