This happened when i was updating the patch. I don't know what happened. Anyone help?
This same thing is happening to me. I get to 73% and then it says I have to restart the launcher. However, this happens everything I start League of Legends up.
I had this problem too, and sadly I think the only way to fix it is to reinstall LoL. You should download a fresh copy, as I got the same problem when I reinstalled with an older copy.
There are a number of fixes in the Bug report section, but none of them worked for me. You can give them a try though since they worked for some people
