Please help Rito

After every single patch I try to open up league of legends and the badge shows up for a few seconds disappears and nothing happens. (so i've found out the only sure way to fix the problem is by completely uninstalling League and then reinstall) Im needing help because i'd like to find out if there is any other way because i end up having to do this process over and over every 2 weeks. Thank you for your time. I hope to get a reply :)
