didnt work, thanks for the suggestion i just dont like getting banned, i love playing i dont mean to quit

Still can´t recconect,deleting the S_OK didnt work.

Having the same issue, details:

I was in the middle of a custom game trying to see how Vi played and what not. After about 4 minutes of play the game started having the reconnect issue come up.

Several minutes of trying to reconnect, LoL crashed out.

I restarted LoL and got a message asking me to Reconnect to a disconnected game.

If I click on the orange Reconnect button it lags until it tells me my turned off firewalls are causing connection issues.

If I don't and simply close out and try to reconnect same issue comes up.

I tried deleting the file as stated on page before this one and it did not work.

It's frustrating, but I'm sure it will be fixed. Sucks though since I got off work early enough to play a bit and apparently fate decided LoL is not in my future right now

^^ I think you need to check your ports and see if they are opened
http://firebind.com/tests/lol
go there and check it out as for the people that did my S_OK trick did you follow it completely I mean did you
if it doesnt launch at first try going into the deploy folder and double click the .exe
(C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\release s\0.0.0.203\deploy) << There should be a folder similar to this I think the number in releases might me different but in there is a League of Legends.exe file run it after your client is closed then restart the client)
file if you dont have it go to the other folder in releases and go into the deploy folder in there and double click the .exe file there

deleting s_ok led to an hour of patching or so and it worked

I'm getting the exact same problem the OP had. It has been going on since the windows update on 12/21.
I have tried the following:
-Deleted multiple folders suggested by mods\
-reinstalled windows 7 to factory settings. (updated all 100+ updates)
-installed directx, .NET framework, NET 4.5, Java
-reinstalled LOL from scratch
-disabled all firewalls
-Changed Proxy settings to 8.8.8.8 and 8.8.4.4

Im now running the firbind test.

I've had now 5+ leaves due to testing if I can get in game after the various changes I've made. Same issue persists.

Firebind test came back successful.

Bump

I'm still getting this
