If you are getting freeze logo of League of Legends after champion select finished and your game won't start and you are getting this msg
"Unable to connect to the server. if you have a firewall, it may be blocking the connection.Please refer to your firewall's documantation."

folow these instructions:

1.Click on Start at bottom left side of the screen
2.Go to "Computer"
3.Open "Control Panel"
4.Go to "Programs and Features"
5.Uninstall League of Legends
6.Uninstall Pando Media Booster
7.Go to place where you had League of Legends installed and remove rest of the files(if there are any)
8.Log in to you account on League of Legends official site
9.Download Client Eu West / Eu Nordic and East
9.RESET YOUR COMPUTER!!!
11.Install the game ON DIFFERENT LOCATION then it was before (if you had game on C:\Program Files\League of Legends make sure to install it on some different location for example D:\Program Files\Riot\League of Legends this is how i did it). This is the key moment of the process if you installed the game on same location you wasted your time. When you reinstall the game you gonna need to Set up your masteries again and you can use this as indicator that you did everything right!!!
12.Please subscribe here if this worked for you ^^


Note: this error mainly happens to users who moved the whole League of Legends folder to some different location(doesn't matter if you did few days ago or 10 patches ago) on them hard drive or installed some additional League of Legends program(as recommended items changer or different skins...) which makes problem with registry keys...so don't do this staff in the future and you won't have problem of this type

Note: this solution might not be the best one but if you have fast internet connection and you are impatient reinstallng the game shouldn't be a problem...

Note: some people claim that this doesn't work for them but still others said it worked... Riot announced that investigation is in progress so we can expect hotfix soon :)
