"league was set back to an older version"

why does this happen at least once a week? not even 2 months ago i reinstalled LoL completely. i removed EVERYTHING that had anything to do with lol and installed it totally fresh because of this problem. yet i still get it AT LEAST once a week. then it has to update AGAIN, sometimes it breaks and TRIES TO UPDATE AGAIN and eventually im lucky to get into the client. wtf is this BS?
