I have had the same issue in the past. Instead of fixing the files and all that, you can force a re-patch which takes a few minutes, but fixes the issue. I won't say anything else, because one could look at it as trolling, so just check out the support page on Leagues site and (if the link doesn't take you directly to the "force a repatch" spot on it, then just scroll down until you see that part, open that tab, and do what it say.
