I had just reinstalled the game to try to fix the issue.

I had to reinstall windows 7 earlier because after windows automatic update my computer crashed constantly and would run extremely slow.

League of legends would not start after the windows automatic update on 5/12. I reinstall windows and it still won't start. Don't know what else to do

Hallo DeMoNic KiLL
make sure your windows is entirely up to date by following this guide:

Note you may need to run it 3/4 times before all updates are caught :-)

Same problem here. I've tried everything; reinstalling LoL, updating windows (repeatedly. THERE ARE NO MORE UPDATES!) and whatnot. Nothing has fixed it. Mods please, if there is a problem with the patch, just let us know. Don't tell us to update things any more, because if nothing has changed on our end since the patch.....its something contained in the patch and need to be fixed.

Same thing happened to me here
when i click play, nothing happens, but then i see that lol launcher is running.

bump

bump. I've been dealing with client problems for a few days now and have no answer. I just keep getting the same advice...

Bump. I made a thread about the same issue. The Wrenchman's link doesn't work btw

re installed everything this sucks
