When the host clicks on start (well i think when he clicks on start)
I get an error. First it freezez my game for 5~10 seconds, Then i get
an error that says

MAESTRO ERROR

There was an error connection with Maestro. League of
Legends will now exit. Pleas try restarting the application

Then i press on "Ok" then the game closes. And i can try it again.
wich will cause the same problem.
is there any way how to solve this problem?

-Greetz

(sorry for maybe any spelling errors)
(I am on my "second computer"=DxDiag.txt i will edit this post tomorow at my other computer with a second dxdiag file if needed)
-------------------------------------------------------------------------------------------------------------------------------------------------
Edit 1: Now i am on my normal computer(=DxDiag 2.txt. But this problem was my fault and is solved see Edit 2),
i had problems with installing. I had the deafult
i changed it. Now i have the game. BUT, when we all are ready. And the game should start.
It crashes, it asks me to reconect, i press reconect then it crashes. It pops up again
and asks me to reconect, i press reconect and again it crashes.

Edit 2: It all works PERFECTLY on the DxDiag 2.txt computer. I thought i ran it as administrator
but i didnt, everything goes good, no lagg. Ping is good, most important no crashes and any error

Edit 3: First i had avast! as my antivirus software, (on DxDiag 2 computer) and everything worked great
Now i have Windows Live OneCare. It blocked some of the conections from League of Legends
But i allowed them, Then I started a game (i where not the host) then it had the same error again.
I Turned the Windows Live OneCare firewall off, and then i was able to play it again without any
problems. So i think most users who got this problem i have (on the DxDiag computer) is
Because something is blocking a conection without saying it, Tunring your Firewall or Antivirus off
will solve the most problems, i think!

Karlbarx, (and maybe more people)

i've been looking trought the forums with all of the same kind of problem
To solve this problem:
1) when in a "Game room" minimize your game
2) wait till the host presses on "start" (dont quickly peek)
3) If he presses start then the game should pop up and you are ready to play
"4)" If you still get the error, then wait, at the top left of the screen is a timer.
When the timer expires. the game will start. This means you cant select
Spells or hero etc. it will be chosen random. But still you can play

I hope that this is fixed in the next patch.
"4)"=new and was as last eddited


Greets!

Thanks for the feedback guys. Make sure to send us logs using the submission tool when this happens.

Make sure you have all Windows updates installed. You can also try reinstalling the game.

I'm having the problem too, using Vista 64 bit. After I install I can run it just fine once, but as soon as I close the launcher and try to get back into it I get this error.

Uninstalling/reinstalling the game allows me to repeat the process. I will submit logs but I don't know how to do that.

Well I 'fixed' it by running the launcher as an administrator.

i think there is nothing wrong with any conection. You are able to play. if you readed above (my second post on this treath) you can play without any problems. only everything is random because you cant pick a champion spells etc.
