League of Legends failed to launch

After today's 45 mb update this happened to me. I try to open the launcher and press play but once I do i get the following message "League of Legends failed to launch" "something unusual happened while trying to launch League of Legends. Try closing and restarting. If the problem persists, contact us at League of Legends support". This had happened to me 4 days ago and reinstalling fixed the issue. However, after today's update this happened again . Is anybody else having this issue or is it my hardware that is causing this issue?
