I have reinstalled the game and i did not have C:\Riot Games\League of Legends\RADS\downloads to delete but i got the other things and still nothing not sure what is up.

I'm having an odd issue as well. I can get onto the client, but if I start a game, it doesnt go to the loading screen and just leaves a blank screen that isn't as wide as my whole screen. I tried quitting and relogging, but I get the exact same result.

Bump. Still having the problem.

So a few days ago I managed to fix this problem by doing my windows update. Well now I am having the same problem again after the patcher seemed to patch something for a split second. Sadly this time my windows update didn't fix the issue.

Had to do a full clean reinstall, but it seems to be working. Any word on whether or not this will be fixed? I really don't wanna spend a whole day doing that again.

Thank you. My girlfriend tried all the steps, and she was able to fix the problem (= ...Although, she says she doesn't know which step did it.

Dear Eamabo...

i have a problem and i really really need ur help to start playing again, however when i click on play and ppl start choosing heroes, in the loading screen my game crash!!! and open a white box says client version 1.00.22, current version 1.00.23. the game close completely pls help will really be thankful

thanks

i think i know how to fix it( worked for me)
go to start\programs\uninstall a program\ find panda media booster\ uninstall\ click LoL
hope this helps

i did windows updates, internet explorer 9 and number 8/8.1 then it worked.

Copy and paste is my best friend right now, just went to the folder, deleted it into oblivion and started up LoL again. Nothing much to it besides that but now instead of the client+patcher and a couple others sitting on the task bar it now starts up and runs.
