Okay so kind of like my last post getting to the point it was this that I kept doing "Update Failed" so I don't know if its just me and saying this "Connection lost to HTTP server. Please check your Internet connection is stable, and that HTTP connections are not being blocked by a firewall.
(Error: 0xc1e90005)" and I really tried everything off of the Wrenchmen's Toolbox and I have no idea what's preventing this from updating I've restarted my computer like 5 times now, attempted re updating like 20 times, repaired it once, re installed it once, deleted files from my RADS/Downloads containing the largest .tmp file hoping for it to re patch, made sure all saftey and firewall settings where accepting League, bu still nothing any ideas or anyone else experience this that knows how to fix it please let me no soon. Other wise I think I might have to wait to the next update . I've put to much money into this game to quit so please help me.

Try to disable Peer to Peer under the Launcher's settings and uninstall Pando Media Booster. Both can cause problems updating your game.

I fixed it somehow
While updating I deleted the file that it stuck in it
I kept doing this every time I receive the message
Try it and tell me

Do you have skype or anything to help me.

same problem here

i fixed it

If you're losing connection, somewhere from your ISP to Riot there is a disconnect. Restart your PC and modem, try again, and if it still doesn't work, go here and post the results please. http://netalyzr.icsi.berkeley.edu/
